自动化测试01

Testing is a major part of any application development life cycle. There are different types of testing based on the application stage – Unit testing, integration testing, system testing etc. Then there are different types of testing process – Manual testing and Automation Testing.

测试是任何应用程序开发生命周期的重要组成部分。 根据应用程序阶段有不同类型的测试-单元测试，集成测试，系统测试等。然后有不同类型的测试过程-手动测试和自动化测试。

手动测试与自动化测试 (Manual Testing vs Automation Testing)

As the name suggests, manual testing requires human effort in running test cases without the use of any tools. Whereas, automation testing is performed by using some tools and test scripts.

顾名思义，手动测试需要人工来运行测试用例，而无需使用任何工具。 而自动化测试是通过使用一些工具和测试脚本来执行的。

 

 

什么是自动化测试？ (What is Automation Testing?)

When testing tools like Selenium, QTP, Load Runner etc. are used to write and execute test cases, it’s called Automation Testing.

当使用诸如Selenium，QTP，Load Runner等测试工具来编写和执行测试用例时，称为自动化测试。

什么是功能自动化测试？ (What is Functional Automation Testing?)

Functional Automation Testing is the process of identifying various functionalities in the project which need to be repetitively tested and then developing and executing Automation Scripts (Programs) to validate the functionalities.

功能自动化测试是确定项目中需要重复测试的各种功能，然后开发和执行自动化脚本（程序）以验证功能的过程。

在此阶段，自动化脚本由测试人员执行。 要执行脚本，我们需要在测试人员运行测试之前输入测试数据。 脚本执行完成后，测试人员将提供详细的测试报告。

保养 (Maintenance)

As new functionalities added each time to the System Under Test with successive cycles, Automation Scripts need to be added, reviewed and maintained for each test cycle release. Maintenance becomes necessary in order to improve the effectiveness of Automation Scripts.

由于每次都有连续的周期向被测系统添加新功能时，需要为每个测试周期版本添加，检查和维护自动化脚本。 为了提高自动化脚本的有效性，必须进行维护。

结论 (Conclusion)

If testing is one time needed then we should go for manual testing. If testing is frequently needed then we should go for automation testing. The right automation tool selection, testing process and right selection of the testing team are the key players for automation testing to be successful.

如果需要一次测试，那么我们应该进行手动测试。 如果经常需要测试，那么我们应该进行自动化测试。 正确的自动化工具选择，测试过程以及测试团队的正确选择是自动化测试成功的关键因素。
