JP7512742B2 - DETECTION PROGRAM, DETECTION METHOD, AND DETECTION APPARATUS - Google Patents

Description

The present invention relates to a detection program, a detection method, and a detection device.

When implementing software, it is essential to run test programs. For this reason, for example, in open source software (OSS), test programs are provided along with the source program. The common language of the OSS community is English, and test programs to check the operation of OSS are also created on the assumption that they will run in the English locale. Here, locale refers to the language set in the program's execution environment.

For example, the judgment statement for the test result is written in English. Therefore, if the test is run in an environment other than the English locale, the output in a language other than English will not match the judgment statement used to judge the test result, and the test will be determined to have encountered an error.

When an error occurs, it is necessary to check whether the cause of the error is the English locale or an environment other than the English locale. In addition, OSS has a large number of test items; for example, the JCK (Java Compatibility Kit) of the OpenJDK (Java Development Kit) has more than 100,000 items. For this reason, the English locale is set and the test program is executed to prevent errors caused by the English locale.

Note that prior art includes technology that automatically detects, corrects, and translates non-localized lines in application source code. Prior art also includes a globalization test management system that uses a set of globalization test operations. This globalization test management system collects a set of globalization data and determines to execute a set of globalization test operations based on the set of globalization data. The globalization test management system then processes the set of globalization data by executing the set of globalization test operations. In response to the processing, the globalization test management system then establishes a set of globalization test output data.

Even if a test program is executed with the English locale set in an environment other than the English locale, the English locale is not set for the sub-process started within the test program. Figure 7 is a diagram showing the locale of the sub-process started within the test program. As shown in Figure 7, for example, in Japan, the Japanese locale is set for the OS (Operating System). For this reason, a test program (TP) created on the assumption that it will be run in the English locale is executed under the English locale setting.

However, the sub-process generated by fork from the main process of the test program references the OS locale setting, and because the OS locale setting is Japanese, it is executed under the Japanese locale. For this reason, an error occurs in the sub-process due to a failure to set the English locale, but it is not possible to determine whether the cause of the error is the English locale or an environment other than the English locale.

In one aspect, the present invention aims to automatically determine whether an error that occurs during the execution of a test program is caused by a failure to set the English locale.

In one aspect, the detection program causes a computer to execute a process of executing a software test, identifying a sub-process for which the locale is not set, and, based on the results of the test execution, identifying tests that have resulted in errors and whose output results are not in English. The detection program then causes the computer to execute a process of detecting an omission of the English locale setting, based on information on the identified sub-process and information on the identified test.

In one aspect, the present invention can automatically determine that an error that occurs during execution of a test program is caused by a failure to set the English locale.

Below, examples of the detection program, detection method, and detection device disclosed in the present application are described in detail with reference to the drawings. Note that the disclosed technology is not limited to these examples.

First, the functional configuration of the detection device according to the embodiment will be described. FIG. 1 is a diagram showing the functional configuration of the detection device according to the embodiment. As shown in FIG. 1, the detection device 1 according to the embodiment has a process monitoring unit 11, a test execution unit 12, a determination unit 13, and a correction unit 14.

The process monitoring unit 11 monitors the startup of a process, and when a process is started, checks the locale setting based on the environment variables or command line arguments of the started process. Here, the environment variables are variables that indicate the environment in which the process is executed. The command line arguments are arguments of the command line that starts the process.

The process monitoring unit 11 checks the locale setting using ps, /proc. [pid], etc. In the case of Java (registered trademark), the command line "-Duser.language=en", "-Duser.country=US", etc. are used to check the locale setting.

If the launched process does not have a locale setting, the process monitoring unit 11 traces the parent processes in order up to the main process, and outputs the identifiers of the processes up to the main process to the locale unset list 16. The process monitoring unit 11 corresponds to the identifying unit described in the claims. Figure 2 is a diagram showing an example of the locale unset list 16. As shown in Figure 2, the locale unset list 16 includes a P identifier, a process ID, a parent process ID, a command line, and environmental variables.

The P identifier indicates whether or not it is a parent process; if it is a parent process it is "P" and if it is not a parent process it is blank. The process ID is an identifier that identifies the process. The process ID "1603" on the first line is the identifier of the launched subprocess. The parent process ID is an identifier that identifies the parent process. The environment variable "LANG=..." is used to check the locale setting.

The test execution unit 12 executes the OSS test program and determines whether an error has occurred. If an error has occurred, the test execution unit 12 notifies the determination unit 13 of the occurrence of the error along with the process ID of the main process of the test program, and if no error has occurred, the test execution unit 12 executes the next test program.

The test execution unit 12 also outputs a log indicating the execution result of the test program to the test result log 17. FIG. 3 is a diagram showing an example of the test result log 17. In FIG. 3, "test result: Failed" indicates that an error has occurred. Also, "¥u3053¥u308c¥u306f¥u3001¥u30c6¥u30b9¥u30c8¥u3067¥u3059¥u3002" indicates a message in Japanese in unicode notation.

The determination unit 13 detects the absence of English locale setting based on the process ID of the main process notified by the test execution unit 12, the locale unset list 16, and the test result log 17. Then, when the determination unit 13 detects the absence of English locale setting, it determines that the cause of the error is the absence of English locale setting.

Specifically, the determination unit 13 identifies a sub-process for which the locale is not set based on the process ID of the main process notified by the test execution unit 12 and the process ID of the main process included in the locale unset list 16.

The determination unit 13 also determines whether the test result log 17 includes a log that is not in English, and if a log that is not in English is included, identifies the test program as a test program whose output result is not in English. Specifically, when a message included in the test result log 17 differs from an expected message, the determination unit 13 determines whether the message is in English based on the unicode of the message.

For example, suppose the expected message is "This is a test." In this case, suppose the message contained in the test result log 17 is "￥u3053￥u308c￥u306f￥u3001￥u30c6￥u30b9￥u30c8￥u3067￥u3059￥u3002" in unicode. Since "￥u3053￥u308c￥u306f￥u3001￥u30c6￥u30b9￥u30c8￥u3067￥u3059￥u3002" is the unicode for "This is a test.", the determination unit 13 determines that the message is not in English.

Alternatively, if the expected message contains the currency unit "$" such as "$123,456" and the message in the test result log 17 contains a different currency unit "￥" such as "￥123,456", the determination unit 13 determines that the message is not in English. Alternatively, if the expected message contains a numerical value such as "4,294,967.00" and the message in the test result log 17 contains "42,94,967.00", the determination unit 13 determines that the message is not in English because the numerical value separators are different. Note that "42,94,967.00" is a numerical value separator in Hindi.

Then, the determination unit 13 can identify the sub-processes for which the locale is not set, and when it is determined that the output result of the test program is not in English, it determines that the English locale is not set, and determines that the cause of the error is the absence of the English locale setting. Note that the determination unit 13 corresponds to the detection unit described in the claims.

If the English locale has not been set, the correction unit 14 sets the English locale for the sub-process identified by the determination unit 13. The correction unit 14 sets the English locale, for example, by correcting the command line arguments that generate the sub-process.

Next, the flow of processing by the detection device 1 will be described with reference to Figs. 4 and 5. Fig. 4 is a flowchart showing the flow of detection processing by the detection device 1. As shown in Fig. 4, the detection device 1 clones the latest test set (test program) (step S1). Here, cloning means copying. Then, the detection device 1 builds the test set (step S2). Here, building means compiling the test set to make it executable.

Then, the detection device 1 starts the process monitoring unit 11 (step S3). The detection device 1 then executes a test (step S4) and determines whether an error has occurred (step S5). If no error has occurred, the detection device 1 then determines whether all tests have been completed (step S6), and if all tests have been completed, ends the detection process. If there is a test set that has not been completed, the detection device 1 returns to step S1.

On the other hand, if an error occurs, the detection device 1 determines whether or not there is a locale not set in the sub-process of the test set based on the locale not set list 16 (step S7). If there is a locale not set, the detection device 1 determines whether or not the output result of the test set is in English (step S8).

If the output result of the test set is not in English, the detection device 1 modifies the test set or changes the test environment (step S9). For example, the detection device 1 modifies the command line that launches a sub-process for which the locale is not set. The detection device 1 then returns to step S2.

On the other hand, if the output result of the test set is in English, or if the subprocess of the test set does not have an unset locale, the detection device 1 outputs an error message (step S10). For example, the detection device 1 uses an error message to request that the cause of the error be investigated and that measures be taken to address the cause of the error.

In this way, the detection device 1 can detect the absence of an English locale setting by determining whether or not the sub-process of the test set has an unset locale and whether or not the output result of the test set is in English. Note that the detection device 1 may switch the order of steps S7 and S8.

Figure 5 is a flowchart showing the flow of monitoring processing by the process monitoring unit 11. As shown in Figure 5, the process monitoring unit 11 performs process monitoring (step S21) and determines whether or not a process has been started (step S22). Then, if a process has not been started, the process monitoring unit 11 returns to step S21.

On the other hand, if a process is started, the process monitoring unit 11 acquires the process ID, command line, and environment variables (step S23), and determines whether the started sub-process has a locale setting based on the command line or the environment variables (step S24). If a locale setting is found, the process monitoring unit 11 returns to step S21.

On the other hand, if there is no locale setting, the process monitoring unit 11 determines whether there is a parent process (step S25), and if there is a parent process, obtains the process ID, command line, and environment variables of the parent process (step S26), and returns to step S25. On the other hand, if there is no parent process, the process monitoring unit 11 analyzes information on the started sub-process and all parent processes, and stores it in the locale unset list 16 (step S27). Then, the process monitoring unit 11 returns to step S21.

In this way, when a sub-process is started and the started sub-process does not have a locale setting, the process monitoring unit 11 analyzes information about the sub-process and all parent processes and stores the information in the locale unset list 16. Therefore, the detection device 1 can use the locale unset list 16 to detect the absence of an English locale setting.

As described above, in the embodiment, the process monitoring unit 11 identifies sub-processes for which the locale is not set during execution of the test program, analyzes information on the sub-processes for which the locale is not set and all parent processes, and stores the information in the locale not set list 16. The determination unit 13 also determines whether the output result of the test program is in English based on the test result log 17. Then, when the determination unit 13 determines that there is a sub-process for which the locale is not set during execution of the test program and that the output result of the test program is not in English, it determines that the English locale is not set. Therefore, the detection device 1 can automatically determine that the cause of an error that occurs during execution of the test program is the absence of the English locale setting.

In addition, in the embodiment, the process monitoring unit 11 identifies that the locale is not set based on the environment variables or command line of the subprocess, so that it can accurately determine that the locale is not set.

In addition, in the embodiment, the determination unit 13 determines that the output result of the test program is not in English by using the code of the message included in the test result log 17, the currency unit included in the message, or the separator of the numerical values included in the message. Therefore, the determination unit 13 can accurately determine that the output result of the test program is not in English.

In addition, in the embodiment, the determination unit 13 determines whether or not there is a sub-process for which the locale is not set, based on the process ID of the main process notified by the test execution unit 12 and the process ID of the main process included in the locale unset list 16. Therefore, the determination unit 13 can accurately determine whether or not there is a sub-process for which the locale is not set.

In the embodiment, the detection device 1 has been described, but a detection program having similar functions can be obtained by implementing the configuration of the detection device 1 using software. Therefore, a computer that executes the detection program will be described.

Fig. 6 is a diagram showing the hardware configuration of a computer that executes a detection program according to an embodiment. As shown in Fig. 6, computer 50 has main memory 51, CPU (Central Processing Unit) 52, LAN (Local Area Network) interface 53, and HDD (Hard Disk Drive) 54. Computer 50 also has super IO (Input Output) 55, DVI (Digital Visual Interface) 56, and ODD (Optical Disk Drive) 57.

The main memory 51 is a memory that stores programs and intermediate results of program execution. The CPU 52 is a central processing unit that reads and executes programs from the main memory 51. The CPU 52 includes a chipset with a memory controller.

The LAN interface 53 is an interface for connecting the computer 50 to other computers via a LAN. The HDD 54 is a disk device for storing programs and data, and the super IO 55 is an interface for connecting input devices such as a mouse and keyboard.

The LAN interface 53 is connected to the CPU 52 via PCI Express (PCIe), and the HDD 54 and ODD 57 are connected to the CPU 52 via SATA (Serial Advanced Technology Attachment). The super IO 55 is connected to the CPU 52 via LPC (Low Pin Count).

The detection program executed in the computer 50 is stored in a DVD, which is an example of a recording medium readable by the computer 50, and is read from the DVD by the ODD 57 and installed in the computer 50. Alternatively, the detection program is stored in a database or the like of another computer system connected via the LAN interface 53, and is read from the database and installed in the computer 50. The installed detection program is then stored in the HDD 54, read into the main memory 51, and executed by the CPU 52.

In the embodiment, a case where an omission of the English locale setting of the OSS is detected has been described, but the detection device 1 may also detect an omission of the English locale setting of other software. In the embodiment, a case where an omission of the English locale setting is detected has been described, but the detection device 1 may also detect an omission of the locale setting of another language.
