JUnit unit test (2) -- JUnit Basics 1. Basic Introduction 1. JUnit is a framework for testing code. The purpose of testing is to ensure that the Code is correct, rather than the code is correct. 2. The test class should not be put together with the target class, but the comp

assertion methods provided by JUnit that judge whether the test results are correct (in class Org.junit.Assert), and we use it to compare the execution result to the expected value "Employee_info". To determine if the test was successful.See how the results work. Right-click on the test class and select Run as

Recently, at the request of the boss, study the spring test related things, and strive to make a convenient use of testing tools, for a spring is not familiar to the JUnit people this is a big pit, swept aside spring test document did not feel any gain, What spring does is just context-sensitive, and the main entrance I want is

Use Junit in the SpringBoot Web Project Create a common Java class. In Junit4, you no longer need to inherit the TestCase class.Because we are a Web project, add annotations to the created Java class: @ RunWith (SpringJUnit4ClassRunner. class) // SpringJUnit support, which introduces Spring-Test framework support! @ SpringApplicationConfiguration (classes = SpringBootSampleApplication. class) // specify th

. Although this can also determine whether to perform the expected exception, but it still has drawbacks, the next will be a comparison to know that, Try...catch method, JUnit can not give you a detailed assertion failure reasons.So what can you do to test the anomaly since JUnit 4? Use @Test (execpted=exception.class)

the normal test. @BeforeClass: For all tests, execute only once and must be public static void; @AfterClass: For all tests, it will be executed once at the end of all test method execution and must be public static void; Hamcrest and TestSuite introduction [4] Hamcrest is a framework that is specifically designed to enhance juni
