This article mainly introduces the IDEA how to use JUnity tools for unit testing related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that you read this IDEA how to use JUnity tools for unit testing article will have a harvest, let's take a look at it.

What is JUnit?

JUnit is a regression testing framework (regression testing framework) for the Java language, established by Kent Beck and Erich Gamma.

Junit testing is also a programmer test, the so-called white-box test, which requires the programmer to know how the code being tested performs its function and what it does.

II. JUnit configuration of IDEA

(1) add dependent jar packages junit-4.12.jar and hamcrest-core-1.3.jar of junit

Maven project pom configuration:

Maven project pom configuration: junit junit 4.12 test org.hamcrest hamcrest-core 1.3

(2) install the junit4 plug-in

(3) choose to use Junit4 by default

(4) configure the output path

Modify Output Path to: ${SOURCEPATH} /.. /.. / test/java/$ {PACKAGE} / ${FILENAME}

(5) modify the test case template. The package name of the package generated in the template needs to be removed from the test.

Third, generate JUnit4 test cases

Method 1: press the shortcut key Alt + Insert on the java class source code block to be tested. Select JUnit Test- > JUnit 4.

Method 2: press the shortcut key Ctrl + Shift + T. Modify the relevant test cases as needed.

Method 3: locate the cursor to the java class source code block to be tested, select code- > Generate, and the following steps are the same as method 1.

Notes used in Test:

@ BeforeClass uses the method of this annotation to execute before the test class is called

@ AfterClass uses this annotated method to execute the number of @ Test annotated methods in a class before the test class is called and exited, and the following annotated methods are called many times

@ Before executes before each @ Test call

@ After executes after each @ Test call

@ Test uses the method of this annotation as a unit test case, which can be declared multiple times in a test class, and each annotation is @ Test only executed once

@ Ignore test cases that are not executed temporarily will be ignored by JUnit4
