Use of JUnit's Rule, and use of JUnit's Rule
Brief Introduction to the simple usage of JUnit Rule. Prepare for source code analysis on JUnit.
Rule is a annotation used to test a unit class. For example, if MyTest defines a field,
such as asserttrue (true) and Assertfalse (false). If you are just going to test the suspend, you can use the Fail method.
· Useassertequalsinsteadofasserttrue:this rule detects the JUnit assertions in object equality. These assertions should are made by the more specific methods, like assertequals.
Translation uses assertequals instead of asserttrue: This rule

White-box test-the test object is regarded as an open box. The logic structure and other information in the program are made public to the tester.
Regression testing-software or environment repair or corrected "retest", which is especially useful for such testing.

Introduction
An example
Let's take a look at an example to learn the characteristics of unit testing for "rules." We have a performance tuning tool, WPA, that evaluates the values of performance-related parameters and recommends optimal values.
IntroductionNeedless to tell, programmers are responsible for the code they write, and not only do you have to make sure that it works properly by compiling, but also to meet the needs and design expectations. Unit testing is one of the effective means of verifying that code behavior meets expectations. But there is no denying that testing is a dull and boring thing, and that testing over and over again is a daunting task. Fortunately, the Unit Test tool JUn

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 compiled class file should be put together to ensure that the product code is separated from t

1. JUnit Introduction
JUnit is a Java testing framework for source code development. It is used to write and run reusable tests. It is an example of xUnit, a unit testing framework system (for java ). It is mainly used for white box testing and regression testing.

JUnit is currently used in a number of large companies or relatively standardized software, and quite a few of the smaller companies do not see the unit test too important. At the big point of the company developers work every day, the first thing is to checkout down the code of their own responsibility from SVN, and then run the unit test, if the unit test passes, then the code is not a problem, then the code block to modify and add, complete and the

JUnit 4 parameter tests allow testing methods by parameter values in the change range. To test the parameters, follow these steps:
Add annotation @ runwith (parameterized. Class) to the test class)
Define the parameter to be tested using the variable range parameter value as a private variable.
Use the private variable declared in the previous step as the input parameter to create the constructor.
. Create a public static method using the @ param
Regular Expression and junit test, regular expression junit
You need to know some regular expression statements, and then write the regular expression statements following the rules. Then, it is about junit testing.
After learning about a document you have read, you can take a look at the document, or search for it later.
The regular expression is a string:
