java - 带有组的 TestNG BeforeMethod

Question

我想知道 @BeforeMethod 对组的用法。在 http://testng.org/javadoc/org/testng/annotations/BeforeMethod.html它说:

alwaysRun: If set to true, this configuration method will be run regardless of what groups it belongs to.

所以我有以下类(class):

public class BeforeTest {
private static final Logger LOG = Logger.getLogger(BeforeTest.class);
@BeforeMethod(groups = {"g1"}, alwaysRun = false)
public void setUpG1(){
    sleep();
    LOG.info("BeforeMethod G1");
}

@Test(groups = {"g1"})
public void g1Test(){
    sleep();
    LOG.info("g1Test()");
}

@BeforeMethod(groups = {"g2"}, alwaysRun = false)
public void setUpG2(){
    sleep();
    LOG.info("BeforeMethod G2");
}

@Test(groups = {"g2"})
public void g2Test(){
    sleep();
    LOG.info("g2Test()");
}


private void sleep(){
    try {
        Thread.sleep(500);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}
}

哪些输出:

BeforeMethod G1
BeforeMethod G2
g1Test()
BeforeMethod G1
BeforeMethod G2
g2Test()

除了我认为 awaysRun 默认情况下为 false 的事实之外，谁能向我解释为什么在每次测试之前调用两个 before 方法，而忽略组？ @Test(skipBeforeMethod = "setUpG1") 之类的东西也可以。

我正在使用 IntelliJ IDEA CE 10.5.2。我也用 gradle 1.0-milestone-3 运行它。

Answer 1

那是因为 groups 标志只表示一个方法是否属于一个组。当启用该组时，它将始终执行，即在所有测试方法之前执行，而不管测试方法属于哪个组。默认情况下，所有组都已启用。

如果您想让该方法只对某些组的测试执行，您需要指定 onlyForGroups。

public class BeforeTest {

    private static final Logger LOG = Logger.getLogger(BeforeTest.class);

    @BeforeMethod(onlyForGroups = { "g1" })
    public void setUpG1() {
        sleep();
        LOG.info("BeforeMethod G1");
    }

    @Test(groups = { "g1" })
    public void g1Test() {
        sleep();
        LOG.info("g1Test()");
    }

    @BeforeMethod(onlyForGroups = { "g2" }, alwaysRun = false)
    public void setUpG2() {
        sleep();
        LOG.info("BeforeMethod G2");
    }

    @Test(groups = { "g2" })
    public void g2Test() {
        sleep();
        LOG.info("g2Test()");
    }

    private void sleep() {
        try {
            Thread.sleep(500);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

输出是

BeforeMethod G1
g1Test()
BeforeMethod G2
g2Test()
