java - Junit5 测试报告程序

Question

我试图理解 Junit5 中的 TestReporter

@BeforeEach
void beforeEach(TestInfo testInfo) {

}

@ParameterizedTest
@ValueSource(strings = "foo")
void testWithRegularParameterResolver(String argument, TestReporter testReporter) {
    testReporter.publishEntry("argument", argument);
}

@AfterEach
void afterEach(TestInfo testInfo) {
    // ...
}

TestReporter中的publishEntry有什么用，

谁能给我解释一下..提前致谢..

“TestReporter”与“TestInfo”一起提供当前测试的实例，这样您就可以获得有关实际测试的信息。然后发布它，在此示例中用作记录器。

StringBuffer 因其可变的、快速的、同步的特性而被使用，这是测试所需要的。

public class TestReporterTest {
    StringBuffer sbtags = new StringBuffer();
    StringBuffer displayName = new StringBuffer();
    StringBuffer className = new StringBuffer();
    StringBuffer methodName = new StringBuffer();

    @BeforeEach
    void init(TestInfo testInfo) {
        className.delete( 0, className.length());
        className.append( testInfo.getTestClass().get().getName());
        displayName.delete( 0, displayName.length());
        displayName.append( testInfo.getDisplayName());
        methodName.delete( 0, methodName.length());
        methodName.append( testInfo.getTestMethod().get().getName());
    }

    @Test
    @DisplayName("testing on reportSingleValue")
    void reportSingleValue(TestReporter testReporter) {
        testReporter.publishEntry( "className  : " + className);
        testReporter.publishEntry( "displayName: " + displayName);
        testReporter.publishEntry("methodName  : " + methodName);
        testReporter.publishEntry("algun mensaje de estatus");
    }

    @Test
    void reportKeyValuePair(TestReporter testReporter) {
        testReporter.publishEntry( "className  : " + className);
        testReporter.publishEntry( "displayName: " + displayName);
        testReporter.publishEntry("methodName  : " + methodName);
        testReporter.publishEntry("una Key", "un Value");
    }

    @Test
    void reportMultiKeyValuePairs(TestReporter testReporter) {
        Map<String, String> map = new HashMap<>();
        map.put("Fast and Furious 8","2018");
        map.put("Matrix","1999");

        testReporter.publishEntry( "className  : " + className);
        testReporter.publishEntry( "displayName: " + displayName);
        testReporter.publishEntry("methodName  : " + methodName);
        testReporter.publishEntry(map);
    }
}

运行测试

timestamp = 2019-11-22T12:02:45.898, value = className  : TestReporterTest
timestamp = 2019-11-22T12:02:45.904, value = displayName: testing on reportSingleValue
timestamp = 2019-11-22T12:02:45.904, value = methodName  : reportSingleValue
timestamp = 2019-11-22T12:02:45.904, value = algun mensaje de estatus


timestamp = 2019-11-22T12:02:45.919, value = className  : TestReporterTest
timestamp = 2019-11-22T12:02:45.920, value = displayName: reportMultiKeyValuePairs(TestReporter)
timestamp = 2019-11-22T12:02:45.920, value = methodName  : reportMultiKeyValuePairs
timestamp = 2019-11-22T12:02:45.921, Fast and Furious 8 = 2018, Matrix = 1999


timestamp = 2019-11-22T12:02:45.924, value = className  : TestReporterTest
timestamp = 2019-11-22T12:02:45.925, value = displayName: reportKeyValuePair(TestReporter)
timestamp = 2019-11-22T12:02:45.925, value = methodName  : reportKeyValuePair
timestamp = 2019-11-22T12:02:45.925, una Key = un Value
