junit example code in java

I learned how to use JUnit for unit testing and log4j for log management. I took a simple note: JUnit JUnit is a Java testing framework for source code development. It is used to write and run reusable tests. This is an example of

String("abc"); String str2=new String("abc"); String str3=null; String str4="abc"; String str5="abc"; int val1=5; int val2=6; String[] expectedArray={"one","two","three"}; String[] resultArray={"one","two","three"}; assertEquals(str1,str2); assertTrue(val1 4. Perform the testThe test case is executed through the Junitcore class, which is the appearance class for JUnit to run t

In our daily business code are not finished, why also write test code, after the completion of the project I can not test it? looks like an increase in the amount of code, but it just helps you reduce the time of the post-test troubleshooting, each team, everyone has a bug indicator, first of all, every time you have so many bug performance is not good to see, an

test, and then test it. But it's a hassle to write test cases every time you need to create a new class.Having said so much, the welfare came. Unit Test Tool--junit. Assist us with unit testing and provide many conveniences. Here's how to use JUnit for unit testing in eclipse.If we write a calculator, we provide some simple calculator functions. The code below,

The example is simple, design a program, enter three integers, determine whether the three integers as the length of the three sides can form a triangle, if you can return the type of the triangle (normal triangles, isosceles triangle or equilateral triangle)Implementation of the code (I write myself casually to do an example, the estimated

that JUnit can then look for the test class inside, and always find the testing case that can be executed and execute it.9. There are two ways to test a private method of a class:1) Modify the access modifier of the method to modify private to default or public (but this is not recommended).2) Use reflection to invoke the private method of the target class in the test class (recommended).10.TestSuite (test suite): Multiple tests can be combined to pe

in our project.The third step is to generate the JUnit Test framework: The package in Eclipse Explorer , right-click on the pop-up menu and select "New à JUnit Test case ". As shown in the following: After clicking "Next", the system will automatically list the methods contained in your class and choose the method you want to test. In this example
