Junit单元测试框架

Selenium3是自动化测试框架

Junit5是单元测试框架

• Junit是针对Java的一个单元测试框架

1.注解

@Test

• 表示当前的方法是一个测试用例

需要先添加依赖

<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
<dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-api</artifactId><version>5.9.1</version><scope>test</scope>
</dependency>

public class JunitTest {@Testpublic void Test01(){System.out.println("学习Junit,Test01");}@Testvoid Test02(){System.out.println("Test02");}
}

@Disable

• 忽略测试用例，直接跳过

    @Disabledvoid Test03() {WebDriver webDriver = new ChromeDriver();webDriver.get("https://www.baidu.com/");webDriver.findElement(By.cssSelector("#s-top-left111 > a:nth-child(6)"));}

@BeforeAll、@AfterAll

    @BeforeAll//在所有的测试用例之前（比如创建驱动、打开网页）static void SetUp(){System.out.println("BeforeAll");}@AfterAll//在所有的测试用例之后（比如关闭浏览器）static void TearDown(){System.out.println("AfterAll");}

@BeforeEach、@AfterEach

    @BeforeEach//在每个测试用例之前执行void BeforeEachTest(){System.out.println("BeforeEach");}@AfterEach//在每个测试用例之后执行void AfterEachTest(){System.out.println("AfterEach");}

2.参数化

parameterized tests

需要引入依赖

<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-params -->
<dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-params</artifactId><version>5.9.1</version>
</dependency>

单参数

    @ParameterizedTest@ValueSource(ints = {1,2,3})void Test04(int num){System.out.println(num);}@ParameterizedTest@ValueSource(strings = {"A","B","C"})void Test05(String number){System.out.println(number);}

会跑三次，每次拿一个数据

CSV获取参数

    @ParameterizedTest@CsvFileSource(resources = "test01.csv")void Test06(String name){System.out.println(name);}

csv文件
张三，李四，王五
张三2，李四2，王五2
张三3，李四3，王五3

运行几次，取决于csv有几行

多参数

    @ParameterizedTest@CsvSource({"1,2,3, ''"})void Test10(String x,String y ,int z ,String q){System.out.println(x);System.out.println(y);System.out.println(z);System.out.println(q);}

方法获取参数

    @ParameterizedTest@MethodSource("Generator")void Test07(int num,String name){System.out.println(num+":"+name);}public static Stream<Arguments> Generator() {return Stream.of(Arguments.arguments(1,"张三"),Arguments.arguments(2,"李四"),Arguments.arguments(3,"王五"));}

测试用例执行顺序

执行指定的顺序

@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
//按照指定顺序执行@Order(4)@Testpublic void Test01() {System.out.println("学习Junit,Test01");}

@TestMethodOrder(MethodOrderer.Random.class)
//随机执行

断言

断言相等

    @ParameterizedTest@ValueSource(ints = {1,2,3})void Test04(int num){System.out.println(num);Assertions.assertEquals(num,1);}

断言不相等

Assertions.assertNotEquals(2,num);

断言为空

        String str = null;Assertions.assertNull(str);String str = "null111";Assertions.assertNull(str);

断言不为空

        Assertions.assertNotNull(str);

3.测试套件

<!-- https://mvnrepository.com/artifact/org.junit.platform/junit-platform-suite -->
<dependency><groupId>org.junit.platform</groupId><artifactId>junit-platform-suite</artifactId><version>1.9.1</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-engine -->
<dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-engine</artifactId><version>5.9.1</version>
</dependency>

通过class运行测试用例

@Suite
@SelectClasses({JunitTest.class,JunitTest01.class})
//按照类写的顺序依次执行
public class RunSuite {}

通过包来运行测试用例

@Suite
@SelectPackages(value = {"package01","package02"})
