Failure tagging is a process for identifying and determining failure causes in software programming modules. It is important for software developers and testers to identify test failure causes in order to correct these failures. With conventional systems, in many cases, failure cause information provided is not comprehensive enough to successfully identify a test failure's root cause. In other words, the failure cause information provided by conventional systems may not allow software developers and testers to correct these failures even though developers and testers may be aware that a problem may exist.
Furthermore, in some situations, failures may be extremely difficult to reproduce during the software programming module testing process due to a specific failure's intermittent nature. For example, conventional systems do not address the issue where a software programming module may not fail during some test execution and yet may fail during other test executions. Thus, the conventional strategy may not address software programming module intermittent failures consistently. This often causes problems because the conventional strategy does not provide a consistent way for developers (and testers), for example, to mark or tag specific failures of interest, and specify actions to take when such failures are encountered during the testing process.
Failure tagging may be provided. This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter. Nor is this Summary intended to be used to limit the scope of the claimed subject matter.
In accordance with one embodiment, a computer-readable medium is provided which stores a set of instructions which when executed performs a method for providing failure tagging. The method executed by the set of instructions may comprise initiating a plurality of tests on a program module and receiving output resulting from the plurality of tests. In addition, the method executed by the set of instructions may include determining that the output resulting from the plurality of tests comprises at least one failure. The at least one failure may comprise one of an unknown failure and a known failure. Then the method executed by the set of instructions may include transmitting results of the plurality of tests, the results indicating the failure.
According to another embodiment, a system for providing failure tagging may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a request to stop a one of a plurality of computers on a failure when the one of the plurality of computers encounters the failure, the request identifying the failure. In addition, the processing unit may be operative to transmit a program module to the plurality of computers configured to run tests on the program module. Moreover, the processing unit may be operative to stop the one of the plurality of computers on the failure when the one of the plurality of computers encounters the failure identified by the request.
In accordance with yet another embodiment, a method for providing failure tagging may comprise receiving a program module change notification in response to a change in programming code corresponding to a program module. In addition, the method may include obtaining the program module associated with the program module change notification. Moreover, the method may comprise initiating a plurality of tests on the program module and receiving output resulting from the plurality of tests. Furthermore, the method may include determining that the output resulting from the plurality of tests comprises at least one failure. The at least one failure may comprise one of an unknown failure and a known failure. In addition, the method may include transmitting results of the plurality of tests, the results indicating the failure.

Failure tagging may be provided. For example, embodiments of the invention may identify and annotate failures in an automation failure tagging system.
Server computing device 105 may include a plurality of test scripts 135. Test scripts 135 may comprise computer programming modules comprising code configured to test, for example, a computer program module 140 without human intervention. For example, a tester may load program module 140 from user computing device 120 to test computing device 125. In addition, the tester may load one of test scripts 135 on to test computing device 125. Once loaded, one of test scripts 135 may be executed on test computing device 125 in order to test computer program module 140.
For example, one of test scripts 135 may test a saved dialogue in computer program module 140 comprising a word processing program. During testing, one of test scripts 135, for example, may function as a user. In other words, one of test scripts 135 may open the word processing program, create a document, and then save the created document. One of test scripts 135 may then report whether the test passed or a failed. In another embodiment, several or all of test scripts 135 may be selected and run on program module 140. If a failure is encountered, the message reported by the test script may comprise a starting point for a developer to investigate that failure. The failure, for example, may be the result of a bug found in program module 140. By identifying the failure, the bug may be fixed by the developer to improve program module 140. Furthermore, by tagging certain failures, when these failures are encountered again or when encountered by other users, the tag may indicate that the failure is known and that corrective actions are being taken by a developer. Consequently, because the testing may be automated, a high testing volume may be performed without a human having to test all the features in program module 140 over and over to see if the features work throughout program module 140's product cycle.
As stated above, embodiments of the invention may provide the ability to tag (i.e. identify and annotate) failures in an automation system. Consistent with embodiments of the present invention, the user may flexibly express a failure tag's scope. For example, the user may provide a specific test scripts for a test or may specify the test for all predefined scenarios. Also, when the user expresses the failure tag's scope, the user may specify using standard SQL wildcards (e.g., *, _, and set notation). In addition, Standard Regular Expression logic found in non-SQL programming languages may be used. In addition, the user may have the ability to hold a machine running a test at a failure point. Other operations may be supported, for example, for known “automation issues” the failure can be re-run, but limit the set of “actions” based on need. Furthermore, consistent with embodiments of the invention, failure tags may be provided a lifecycle. For example, failure tags may be configured to expire after a period of time or may only apply to certain versions of the product. This may encourage users to keep failure tags up to date. Moreover, embodiments of the invention may allow users to retroactively tag failures matching a particular failure tag's criteria to aid in general failure investigation by other users of the automation system.
Network 110 may comprise, for example, a local area network (LAN) or a wide area network (WAN). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet. When a LAN is used as network 110, a network interface located at any of the computing devices may be used to interconnect any of the computing devices. When network 110 is implemented in a WAN networking environment, such as the Internet, the computing devices may typically include an internal or external modem (not shown) or other means for establishing communications over the WAN. Further, in utilizing network 110, data sent over network 110 may be encrypted to insure data security by using encryption/decryption techniques.
In addition to utilizing a wire line communications system as network 110, a wireless communications system, or a combination of wire line and wireless may be utilized as network 110 in order to, for example, exchange web pages via the Internet, exchange e-mails via the Internet, or for utilizing other communications channels. Wireless can be defined as radio transmission via the airwaves. However, it may be appreciated that various other communication techniques can be used to provide wireless transmission, including infrared line of sight, cellular, microwave, satellite, packet radio, and spread spectrum radio. The computing devices in the wireless environment can be any mobile terminal, such as the mobile terminals described above. Wireless data may include, but is not limited to, paging, text messaging, e-mail, Internet access and other specialized data applications specifically excluding or including voice transmission. For example, the computing devices may communicate across a wireless interface such as, for example, a cellular interface (e.g., general packet radio system (GPRS), enhanced data rates for global evolution (EDGE), global system for mobile communications (GSM)), a wireless local area network interface (e.g., WLAN, IEEE 802.11), a bluetooth interface, another RF communication interface, and/or an optical interface.
An embodiment consistent with the invention may comprise a system for providing failure tagging. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to initiate a plurality of tests on a program module and to receive output resulting from the plurality of tests. In addition, the processing unit may be operative to determine that the output resulting from the plurality of tests comprises at least one failure. The at least one failure may comprise one of an unknown failure and a known failure. Furthermore, the processing unit may be operative to transmitting results of the plurality of tests, the results indicating the failure.
Another embodiment consistent with the invention may comprise a system for providing failure tagging. The system may comprise a memory storage and a processing unit coupled to the memory storage. The processing unit may be operative to receive a request to stop a one of a plurality of computers on a failure when the one of the plurality of computers encounters the failure, the request identifying the failure. In addition, the processing unit may be operative to transmit a program module to the plurality of computers configured to run tests on the program module. Moreover, the processing unit may be operative to stop the one of the plurality of computers on the failure when the one of the plurality of computers encounters the failure identified by the request.
With reference to
Server computing device 105 may have additional features or functionality. For example, server computing device 105 may also include additional data storage devices (removable and/or non-removable) such as, for example, magnetic disks, optical disks, or tape. Such additional storage is illustrated in
Server computing device 105 may also contain a communication connection 216 that may allow server computing device 105 to communicate with tester computing devices 115, such as over network 110 in a distributed computing environment, for example, an intranet or the Internet. Communication connection 216 is one example of communication media. Communication media may typically be embodied by computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and includes any information delivery media. The term “modulated data signal” may describe a signal that has one or more characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media may include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), infrared, and other wireless media. The term computer readable media as used herein may include both storage media and communication media.
As stated above, a number of program modules and data files may be stored in system memory 204, including operating system 205. While executing on processing unit 202, failure tagging programming module 220 may perform processes including, for example, one or more method 300's stages as described below. The aforementioned process is an example, and processing unit 202 may perform other processes. Other programming modules that may be used in accordance with embodiments of the present invention may include electronic mail and contacts applications, word processing applications, spreadsheet applications, database applications, slide presentation applications, drawing or computer-aided application programs, etc.
From stage 310, where computing device 105 receives the program module change notification, method 300 may advance to stage 320 where computing device 105 may obtain program module 140 associated with the program module change notification. For example, in response to receiving the program module change notification, computing device 105 may connect to user computing device 120 over network 110 and obtain program module 140.
Once computing device 105 obtains program module 140 associated with the program module change notification in stage 320, method 300 may continue to stage 330 where computing device 105 may initiate a plurality of tests on program module 140. For example, computing device 105 may send, over network 110, program module 140 to each of plurality of test computing devices 115. Furthermore, computing device 105 may send, over network 110, test scripts 135 to each of plurality of test computing devices 115. Sever computing device 105 may have a different set of test scripts for any type programming model to be tested. For example, if programming module 140 comprises a spreadsheet application, a first set of test scripts may be sent to test computing devices 115. If, however, programming module 140 comprises a word processing application, a second set of test scripts may be sent to test computing devices 115. Test scripts 135 may be designed to test one or more different aspects of programming module 140. For example, a test script may be designed to create and save a file, while another test script may be designed to simulate sending a document to a printer. In other words, test scripts 135 may comprise a set of programs configured to test one or more aspects of program module 140.
Another example may be that a singular test may be executed repeatedly on a program module to try to force a known, rare, failure to be encountered in order to hold the machine for investigation. In this example, the program module may not be altered by the developer because its issue has been present for a while and has been difficult to obtain a failure to debug.
When initiating the plurality of tests on program module 140, computing device 105 may send test scripts 135 to test computing device 125 and to test computing device 130. Accordingly, each of test computing device 125 and test computing device 130 may substantially concurrently run test scripts 135 on program module 140. In addition, each of test computing device 125 and test computing device 130 may repeatedly run test scripts 135 on program module 140. For example, test computing device 125 may run test scripts 135 300 times on program module 140 and test computing device 130 may run test scripts 135 200 on times program module 140.
After computing device 105 initiates the plurality of tests on program module 140 in stage 330, method 300 may proceed to stage 340 where computing device 105 may receive output resulting from the plurality of tests. For example, test computing device 125 and test computing device 130 may send output over network 110 to server computing device 105 indicating whether program module 140 passed or failed the tests.
From stage 340, where computing device 105 receives output resulting from the plurality of tests, method 300 may advance to stage 350 where computing device 105 may determine that the output resulting from the plurality of tests comprises at least one failure. The at least one failure may comprise an unknown failure or a known failure. A known failure may comprise a failure type that has been encountered before. For example, a failure may have been identified during a previous test. This previously identified failure may have been analyzed and “tagged” by a software developer who has taken on the responsibility to fix a programming bug that may have caused this particular failure. In this case, it may be important to note that the failure has been previously identified (i.e. tagged) and efforts are being made to fix it. Accordingly, the output received resulting from the plurality of tests may be compared to a database comprising known failures. This comparison may be made to determine if a similar failure exists in the database as a tagged failure.
In another embodiment, as the test logs a failure, the resulting failure may be processed to identify if it is a known failure. If the known failure has been set to hold the machine for debugging, then this action may be performed. If there is no action to perform at this point, then the test may be allowed to continue execution.
Once computing device 105 determines that the output resulting from the plurality of tests comprises at least one failure in stage 350, method 300 may continue to stage 360 where computing device 105 may transmit results of the plurality of tests. The results may indicate the failure. For example, server computing device 105 may send (e.g. via e-mail) user computing device 120 over network 110 the results. The results may indicate any situations in which program module 140 failed any of test scripts 135. Furthermore, the results may indicate if any of the failures are known or unknown.
After computing device 105 transmits the results of the plurality of tests in stage 360, method 300 may proceed to stage 370 where computing device 105 may receive data configured to tag an unknown failure as a known failure. For example, a user, comprising the software developer who made the aforementioned changes to the programming code corresponding to program module 140, may review the results received from computing device 105. Upon reviewing the results, the user may wish to “tag” an unknown failure shown in the results. For example, the user may determine that the unknown failure was caused by the aforementioned changes to the programming code corresponding to program module 140 that the software developer made. Consequently, the software developer may take ownership of fixing a defect in the programming code corresponding to program module 140 that may have caused the unknown failure. Accordingly, the software developer may provide to computing device 105, data configured to tag the unknown failure as a known failure. The data may associate the software developer tagging the unknown failure with the known failure. Computing device 105 may receive the data configured to tag the unknown failure as a known failure. In addition, computing device 105 may tag the unknown failure as a known failure based upon the received data.
Moreover, computing device 105 may configure the tag to expire after a predetermined amount of time. For example, the software developer associated with the tag as described above may fix a bug in the program module 140 that may have caused the unknown failure now tagged as a known failure. When this tagged failure is encountered again in any subsequent testing, the tag may be identified as a known (i.e. tagged) failure. However, if for any reason the software developer does not fix the bug, the tag may expire after the predetermined amount of time passes. After the tag expires, and if the failure associated with this expired tag is encountered again in any subsequent testing, the tag will be identified as an unknown failure. Once computing device 105 receives the data configured to tag an unknown failure as a known failure in stage 370, method 300 may then end at stage 380.
Consistent with another embodiment of the invention, computing device 105 may receive a request to stop one of plurality of test computing devices 115 on a failure when the one of the plurality of computers encounters the failure. The request may identify the failure. For example, as described above with respect to stage 370, the software developer may take ownership of fixing a bug in the programming code corresponding to program module 140 that may have caused an unknown failure the software developer subsequently tagged. In an effort to fix the aforementioned bug, the software developer wishing to fix the bug may want to have the computing device (or devices) within plurality of test computing devices 115 to stop when the failure associated with the bug is encountered.
After receiving the request, computing device 105 may transmit program module 140 to plurality of test computing devices 115 configured to run tests on program module 140. Subsequently, computing device 105 may stop one of the plurality of test computing devices 115 on the failure when the one of the plurality of test computing devices 115 encounters the failure identified by the request. After the one of the plurality of test computing devices 115 is stopped, computing device 105 may transmit a notice to the software developer. The notice may be configured to indicate, for example, that the one (or more) of the plurality of test computing devices 115 encountered the failure identified by the request, that the one (or more) of the plurality of test computing devices 115 is being held for the software developer, and information identifying the one of the plurality of test computing devices 115. As a result, the software developer may then go to the laboratory where the one of the plurality of test computing devices 115 is located. The user may then study or investigate the state of the one of the plurality of test computing devices 115 stopped in order to fix the aforementioned bug.
