TestNG中case之间的依赖关系

我们写单元测试的时候，可能会遇到一条case依赖另外一条case，比如我现在用一个xml文件生成html文件，但是这个xml文件就是另外一条case生成的。所以我们需要定义一种依赖就是生成html的case要在生成xml文件的case之后生成，看看有什么解决的方法

dependsOnGroups

生成xml的单测case如下：

@Test(groups = { "unittest","androidtestresult" })    public void generateAndroidXmlTestResult() 

生成html的单测case如下：

@Test(groups = { "unittest" }, dependsOnGroups = { "androidtestresult" })    public void generatorAndroidReportByMuiltDirTest() 

在需要依赖的case上定义了dependsOnGroups属性，里面就是被依赖case所在的组，这样当该case执行的时候，被依赖组中的case都会被执行。而我只是给groups定义为androidtestresult，所以androidtestresult组中只有一条case为generateAndroidXmlTestResult，所以只会执行这条case。

执行结果：

但是这种方式还要规定你依赖的群组中只有一条case，不太好，我们找找是否可以直接依赖单条case的。
