问题 The code below is a selenium script I created with the Selenium IDE, I'm trying to get it to click 250 pixels from the technology button which should click the 'education' tab.

@WebMvcTest creating more than one Controller for some reason

由 你离开我真会死。 提交于 2021-01-29 06:06:34
问题 I'm trying to create a controller test with @WebMvcTest , and as I understand, when I put @WebMvcTest(ClientController.class) annotation of the test class it should not create a whole lot of beans, but just ones that this controller requires. I'm mocking the bean this controller requires with @MockBean , but somehow it fails with an exception that there's 'No qualifying bean' of another service that does not required by this controller but by another. So this test is failing: @RunWith

一文让你快速上手 Mockito 单元测试框架

前言 在计算机编程中，单元测试是一种软件测试方法，通过该方法可以测试源代码的各个单元功能是否适合使用。为代码编写单元测试有很多好处，包括可以及早的发现代码错误，促进更改，简化集成，方便代码重构以及许多其它功能。使用 Java 语言的朋友应该用过或者听过 Junit 就是用来做单元测试的，那么为什么我们还需要 Mockito 测试框架呢？想象一下这样的一个常见的场景，当前要测试的类依赖于其它一些类对象时，如果用 Junit 来进行单元测试的话，我们就必须手动创建出这些依赖的对象，这其实是个比较麻烦的工作，此时就可以使用 Mockito 测试框架来模拟那些依赖的类，这些被模拟的对象在测试中充当真实对象的虚拟对象或克隆对象，而且 Mockito 同时也提供了方便的测试行为验证。这样就可以让我们更多地去关注当前测试类的逻辑，而不是它所依赖的对象。 1 生成 Mock 对象方式 要使用 Mockito，首先需要在我们的项目中引入 Mockito 测试框架依赖，基于 Maven 构建的项目引入如下依赖即可： <dependency> <groupId>org.mockito</groupId> <artifactId>mockito-core</artifactId> <version>3.3.3</version> <scope>test</scope> </dependency>

Hibernate isolated integration tests

问题 I'm a little bit new to hibernate, so I started with simple things. According to F.I.R.S.T test principles, unit tests must be I - isolated. I'm trying to apply it to integration tests for repository layer (Hibernate\JPA) using @Transactional annotation: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = RepositoryConfig.class) @Transactional public class EmployeeRepositoryTest extends AbstractRepositoryTest { @Autowired private IEmployeeRepository employeeRepository;

Get current Spring transaction in JUnit and commit it

由 梦想的初衷 提交于 2021-01-28 21:44:15
问题 is it possible to get current Spring transaction in JUnit? I want to test JPA in DAO. And DAO do not have transactions. In tests spring create transaction for every method. I want transaction to be commited somewhere in the middle of test. Need it to test DB status. Only solution I found is to create @Rule for every method. 回答1: You can use TestTransaction in order to manage spring test transactions: TestTransaction.flagForCommit(); TestTransaction.end(); This will flag the current
