Powermock supports Easymock and Mockito.Ii. introduction to PowermockThe Powermock has two important annotations:– @RunWith (Powermockrunner.class)– @PrepareForTest ({Yourclasswithegstaticmethod.class})If you do not use annotation @preparefortest in your test case, you can do so without annotating @runwith (Powermockrunner.class) and vice versa. When you need to use Powermock powerful features (mock stati

This article will briefly describe how to use powermock and Mockito to mock1. Constructors2. Static functions3. Enumeration implementation of the Singleton4. Select the parameter value as the return value of the function5. Change the value of the method parameter in the call to the mock-out methodA brief explanation: Mockito has actually been able to meet most of the requirements, but its implementation mechanism is to use Cglib to dynamically create an instance of the interface class. However,

At this point, one of our options is to modify the source code. In object-oriented languages, we have always stressed flexible and independent code structures. If a class is hard to be tested, it may be a symbol of poor code structure. Obviously, the sayhi method depen

The previous article describes how to let Surefire,failsafe and Jacoco maven plugin How to combine configuration, this article specifically explains how to use the Powermock agent to solve coverage incompatibility problems.First add Powermock agent maven dependency in POM Note:it ' s recommended that's put powermock-module-junit4-rule-agent before JUnit in the classpath. (Remember to put this dependency before JUnit). Next, modify the previous test code:Implementation prior to modification @Ru

Note that the first two lines of the 2 annotations @RunWith and @PrepareForTest The @RunWith is simple, the back is always Powermockrunner.class @PrepareForText need to add the class name of the calling constructor, not the class itself that has the constructor. In the following example, the class we want to test is: helper, which invokes the constructor of the Somthing class in the helper class to create the instance. @RunWith (Powermockrunner.cl

now familiar to everyone. Currently, Powermock only extends EasyMock and Mockito, and needs to be used with EasyMock or Mockito mates.Powermock can be downloaded in https://code.google.com/p/powermock/, this article takes Powermock+mockito as an example, using MAVEN, add the following dependencies, MAVEN will automatically introduce the Mockito package.Now for example the use of Powermock, suppose there is a class that needs to be modeled as follows:public class Class2mocked {public static i
