Software testing is to use testing tools to test the function and performance of products according to the test scheme and process, and even write different test tools as needed, design and maintain the test system, and analyze and evaluate the possible problems of the test scheme. After executing test cases, failures need to be tracked to ensure that the developed product is suitable for the requirements. Among them, software compatibility testing refers to testing the dependence of software on its operating environment to verify whether the software can run in all desired environments.
1. Hardware compatibility test
Hardware compatibility testing generally considers two aspects: one is that different hardware configurations may affect the performance of the software, and the other is that if the software uses certain functions of certain hardware, it must be tested for compatibility. The hardware compatibility test is as follows:
1. Compatibility test with the whole machine
Considering the operation of the software, it is necessary to test common hardware configurations to determine that the software can run in multiple hardware configuration environments. If the software has high hardware configuration requirements, it is also necessary to test its sensitivity.
2. Compatibility test with boards and peripherals
If the software requires direct access to certain types of boards and peripherals, interface calls to those boards and peripherals often need to be tested to ensure that access to these interfaces is available for all models of boards and peripherals.
2. Software compatibility test
Software compatibility testing mainly considers the following questions:
1. Compatibility with the operating system
If a software can run on multiple operating systems, it needs to be tested for compatibility on different versions of the same operating system platform.
2. Compatibility with databases
If the software needs to support different databases, compatibility testing is usually required for different database products, and compatibility testing is also required for different versions if the same database product contains multiple versions. At present, most of the commonly used database products support SQL standard databases, such as MS SQL Server, Oracle, ODBC, JDBC, etc., but different databases support different SQL standards. If the software under test supports ODBC and JDBC and connects to the actual database through ODBC and JDBC, the compatibility test of the software should include testing ODBC and JDBC, and testing the actual database.
3. Compatibility with browsers
Compatibility issues often arise for different browsers and different versions of browsers, such as certain HTML tags can only be used on certain browsers; Some specific scripts and plugins are only available for certain browsers. For example, Active X is only supported by Internet Explorer, and different browsers have different security settings, so it is necessary to test whether the browsers can provide appropriate security settings for using the web application.
4. Compatibility with middleware
More and more software requires middleware support to function. The middleware developed by different manufacturers is very different, and it is difficult for software running on one middleware to run on other middleware. Therefore, compatibility testing with middleware is mainly tested for different versions of the same product. In addition, some applications may need to run on different J2EE middleware.
5. Compatibility with other software
Software always needs to interact with other software in operation, and any interaction problems may cause problems with the operation of the software, so compatibility testing should be carried out for software that may interact with this software.
6. Compatibility with platform software
We can divide platform software into two types: operation platform and development platform. For the running platform, the compatibility test mainly includes testing the compatibility of the platform software with the application software running on it, and for the development platform, the compatibility test includes testing the compatibility of the developed software with the corresponding environment.
3. Data compatibility test
Data compatibility mainly includes the following:
1. Data compatibility testing between different versions
A software system will have a series of versions throughout its lifecycle, so compatibility testing is an important aspect when testing whether a new version of the software is compatible with the data of an older version.
2. Data compatibility test between different software
Data compatibility testing exists not only between different versions of the same software, but also between different software. Usually different software in a series is integrated through the agreed data format, and different software is integrated through the standard data format, at this time, it is necessary to check whether the software under test can interact correctly through various data in the composite data format for the corresponding one or more data formats.
Conclusion: In actual software development, software usually needs to run in many different software and hardware environments, but because any software depends more or less on the running environment, the difference in environment may lead to different results when the software runs in different environments, so it is important to test the compatibility of the software. However, not every software needs to be tested for all compatibility items, and in actual testing, it is necessary to select according to the software type, requirement positioning and test environment, and adjust and expand the test scheme. It should also be noted that for customized systems, compatibility testing should be carried out as early as possible, otherwise after the system is put into use, the risk and investment of compatibility testing will increase as the data in the system increases. Often, if there are many variations in the desired operating environment, compatibility will be complex, otherwise compatibility is likely to be problem-free and compatibility testing will be very simple. Therefore, according to the requirements of different software for their operating environment, different software compatibility tests should be carried out to ensure the normal operation of the software and play its maximum role.
