java - 未执行测试 - JUnit 5 以编程方式 + mvn exec
问题描述
我正在一个 Selenium 自动化项目中运行回归测试。测试是用 JUnit 5.5.1 编写的。没有 Surefire 或 Failsafe 插件（测试不在 src/test/java 下，它们位于 src/main/java 下，因为不是单元测试）。
问题是当我使用 .bat 文件（执行 mvn exec:java ...）运行代码时，没有执行任何测试，我不确定我的配置是否完全正确。在最坏的情况下，这是我正在使用的 JUnit 版本的错误（我从 1 周开始就在使用 JUnit 5，所以我还不熟悉某些配置）。我非常感谢在 JUnit 5 方面比我更有经验的人的帮助。
这就是我执行 .bat 文件后得到的结果。.bat 文件包含以下内容：
mvn clean install exec:java -Dexec.args="'%some_env_as_arg_1%' '%some_env_as_arg_2%'" -DsomeExpectedEnv=%someExpectedEnv%

使用 junit-plattform-launcher lib 以编程方式执行测试：
public static void main(String[] args) {
try {
evaluateArgs(args);
String csvFilePath = SetupProps.getCsvFilename();
//This will take each of test case defined in CSV file as an String array
String[] testCasesIDs = readTestCasesFromCSVFile(csvFilePath);
//For each one of the test cases ID finded, will be instantiate its own Test Case class
loadTestCases(testCasesIDs);
//Starts the execution of each test case
SummaryGeneratingListener listener = new SummaryGeneratingListener();
for (AbstractITCase testCase : testCasesList) {
runTestProgramaticallyInJUnit5(listener, testCase);
}
TestExecutionSummary summary = listener.getSummary();
summary.printTo(new PrintWriter(System.out));
} catch (DOKAAutomationException e) {
LOGGER.error("Error catched. Process aborted.", e);
} catch (Exception e) {
LOGGER.error("Unexpected error catched in application. Process aborted.", e);
}
}
private static void runTestProgramaticallyInJUnit5(SummaryGeneratingListener listener, AbstractITCase testCase) {
LOGGER.info("-- Execution of test {} started --", testCase.getClass().getSimpleName());
LauncherDiscoveryRequest request = LauncherDiscoveryRequestBuilder.request()
.selectors(DiscoverySelectors.selectClass(testCase.getClass())).build();
Launcher launcher = LauncherFactory.create();
TestPlan testPlan = launcher.discover(request);
launcher.registerTestExecutionListeners(listener);
launcher.execute(request);
LOGGER.info("-- Execution of test {} finished --", testCase.getClass().getSimpleName());
}
所有测试类的超级类：
@ExtendWith(SpringExtension.class)
@IntegrationTest
@ContextConfiguration(classes = {AppConfig.class})
public abstract class AbstractITCase {
@RegisterExtension
protected static ReporterHandlerExtension runnerExtension = new ReporterHandlerExtension
.Builder()
.reports(extent)
.driver(WebDriverUtils.getWebDriver())
.build();
static {...}
@Autowired
protected WebDriver driver;
}
登录测试类：
@PropertySource("classpath:test_values/login/login_ok_values.properties")
@DisplayName("Login Sucessful Scenario")
public class LoginITCase extends AbstractITCase {
private final static Logger LOGGER = LoggerFactory.getLogger(LoginITCase.class);
@Autowired
LoginPage loginPage;
@Test
@DisplayName("Entering user and password")
@Order(1)
public void enterUsernameAndPassword() {
LOGGER.info("-- enterUsernameAndPassword method started");
driver.get(SetupProps.getDokaUrl());
Assertions.assertTimeout(Duration.ofMinutes(1), () -> {
loginPage.enterUsernameAndPassword();
});
LOGGER.info("-- enterUsernameAndPassword method finished");
}
@Test
@DisplayName("Click button to login")
@Order(2)
public void clickButtonOkToLoggin() {
LOGGER.info("-- clickButtonOkToLoggin method started");
Assertions.assertTimeout(Duration.ofMinutes(1), () -> {
loginPage.clickButtonToLogin();
loginPage.isLoginSucessful();
});
LOGGER.info("-- clickButtonOkToLoggin method finished");
}
}
封装测试行为的接口（由 AbstractITCase 类实现并继承给它的所有子类：
@Component(value = "loginTest")
@Tag("IntegrationTest")
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE_USE)
public @interface IntegrationTest {
}
解决方案
问题是我注册的扩展在内部引发了一个错误，与 JUnit 5 和 Maven 上的配置无关。
创建此扩展是为了在测试的生命周期中处理 ExtentReports API，创建报告测试对象，逐步记录结果，最后将报告刷新到 HTML 文件。
