TestNG 中测试的执行顺序 [英] Order of execution of tests in TestNG

问题描述

如何在TestNG中自定义测试的执行顺序?

How to customize the order of execution of tests in TestNG?

例如:

public class Test1 {
  @Test
  public void test1() {
      System.out.println("test1");
  }

  @Test
  public void test2() {
      System.out.println("test2");
  }

  @Test
  public void test3() {
      System.out.println("test3");
  }
}

在上面的套件中，测试的执行顺序是任意的.对于一次执行，输出可能是:

In the above suite, the order of execution of tests is arbitrary. For one execution the output may be:

test1
test3
test2

如何按照编写的顺序执行测试?

How do I execute the tests in the order in which they've been written?

推荐答案

这会起作用.

@Test(priority=1)
public void Test1() {

}

@Test(priority=2)
public void Test2() {

}

@Test(priority=3)
public void Test3() {

}

priority 鼓励执行顺序，但不保证前一个优先级已经完成.test3 可以在 test2 完成之前开始.如果需要保证，则声明一个依赖项.

priority encourages execution order but does not guarantee the previous priority level has completed. test3 could start before test2 completes. If a guarantee is needed, then declare a dependency.

与声明依赖项的解决方案不同，即使一个测试失败，使用 priority 的测试也会执行.根据 文档.

Unlike the solutions which declare dependencies, tests which use priority will execute even if one test fails. This problem with dependencies can be worked around with @Test(...alwaysRun = true...) according to documentation.
