Question

我想在BeforeClass中使用Parameters作为具有不同角色的其他用户登录。

我用：

JUnitParams 1.0.2
junit 4.12
Selenium wedbriver 2.53.1

这是我的代码 FirefoxLogin.java

public class FirefoxLogin {    

public static WebDriver login(User user, String language){
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.example.org");        

    WebElement loginField = driver.findElement(By.id("username"));
    WebElement passwordField = driver.findElement(By.id("password"));
    WebElement commit = driver.findElement(By.id("kc-login"));

    loginField.sendKeys(user.getLogin());
    passwordField.sendKeys(user.getPassword());
    commit.click();
    setLanguage(driver, user, language);
    return driver;
}

public static void logout(WebDriver driver) {
    driver.findElement(By.linkText("Logout")).click();
    driver.quit();
}

protected static void setLanguage(WebDriver driver, User user, String language) {
    // method to set language
}
}

User.java

public class User {
public static final User USERONE = new User("loginOne", "passwordOne");
public static final User USERTWO = new User("loginTwo", "passwordTwo");

private String login;
private String password;

User(String login, String password) {
    this.login=login;
    this.password=password;
}

public String getLogin(){
    return login;
}

public String getPassword(){
    return password;
}

public static List<User> getUser() {
    List<User> users = new ArrayList<>();
    users.add(USERONE);
    users.add(USERTWO);

    return  users;
}

}

AddFieldTest.java

@RunWith(JUnitParamsRunner.class)
public class AddFieldTest {
private static WebDriver driver;
private static final Object[] userValues() {
    return $(
            $(User.USERONE, "en"),
            $(User.USERTWO, "en")
    );
}

@Parameters(method = "userValues")
@BeforeClass
public static void init(User mUser ,String mLanguage) {
     driver = FirefoxLogin.login(mUser, mLanguage);
}

@AfterClass
public static void close() {
    FirefoxLogin.logout(driver);
}

private Object[] valuesForTest() {
    return $(
            $("street", null, null),
            $(null, "city", null),
            $(null, null, "country"),
            $("ulica", "city", null),
            $("ulica", "city", "country")
    );
}

@Test
@Parameters(method = "valuesForTest")
public void test(String mStreet, String mCity, String mCountry)  {

}

}

这是mu输出： java.lang.IllegalArgumentException：参数数量错误

Answer 1

在这种情况下，异常是由init方法的参数引起的 - 它们是不允许的。此外，您无法使用@BeforeClass注释@Parameters方法 - 请参阅讨论here。

JUnitParams仅支持测试方法的参数化。

@BeforeClass意味着应该是一次性动作   准备测试系统。

如何在@BeforeClass中使用@Parameters for Junit
