我正在使用TestNG运行自动化Selenium测试。当我作为TestNG Suite运行时,一切正常。但是当我作为Maven Test运行时,它们会失败。我非常困惑为什么他们会在一种情况下而不是另一种情况下工作。以下是测试的总体布局:
Base.java
public class Base {
public WebDriver driver = null;
public WebDriver getLocalDriver() {
driver = new FirefoxDriver();
return driver;
}
TestBase.java
public class TestBase extends Base {
@BeforeTest
public void beforeTest() {
Base b = new Base();
driver = b.getLocalDriver();
}
@AfterTest
public void afterTest() {
driver.quit();
}
LoginTests.java
public class LoginTests extends TestBase {
@Test
public void TestOne() {
driver.get("http://www.company.com");
// ^^^ driver == null right here (line 28)
}
错误讯息:
java.lang.NullPointerException
at com.company.automation.ecom.tests.LoginTests.TestOne(LoginTests.java:28)

我非常困惑为什么他们会在一种情况下工作而不是 另一个。
当我第一次发现TestNG(好)使用多线程时,我也是如此。
尝试将@BeforeTest
和@AfterTest
注释更改为@BeforeMethod
和@AfterMethod
。这将是最简单的解决方案。
除了坚持WebDriver
静态ThreadLocal
可能是成功的关键。
考虑一下:
public class TestBase {
protected static ThreadLocal<WebDriver> webDriver = new ThreadLocal<WebDriver>();
protected String abc;
@BeforeMethod
public void setUp(){
System.out.println("I am in setUp method.");
//WebDriver instantiation etc.
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized", "--disable-cache");
webDriver.set(new ChromeDriver(options));
webDriver.get().manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}
@AfterMethod
public void tearDown(){
System.out.println("I am in tearDown method.");
//You can clean up after tests.
//webDriver.get().quit();
webDriver.get().quit();
}
}
在两个单独的文件中:
public class Test1 extends TestBase {
@Test
public void goToGoogle() {
System.out.println("Google");
String googleURL = "http://google.com/";
webDriver.get().get(googleURL);
assertTrue(webDriver.get().getCurrentUrl().contains("google"), "We are on Google!");
}
}
和
public class Test2 extends TestBase {
@Test
public void goToStackOverflow() {
System.out.println("SO!");
String stackOverflowAddress = "http://stackoverflow.com/";
webDriver.get().get(stackOverflowAddress);
assertTrue(webDriver.get().getCurrentUrl().contains("stack"), "We are on SO!");
}
}

您可以使用的伴侣:
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-testng</artifactId>
<version>3.0.0-M3</version>
</dependency>
我的maven测试是这样执行的。
谢谢
