In this post under Mockito, I will show with example how to stub a non-static void method to throw an exception. For our example I will use the below classes. PersonDAO package package10; import java.sql.SQLException; public class PersonDAO { public void save() throws SQLException { System.out.println("Data is saved"); } } PersonManager package package10; import java.sql.SQLException;…… Continue reading Stubbing a non-static void method to throw an exception

In this post under Mockito, I will show with example how to stub a non-static void method to do nothing. For our example, I will use the below class MyCustomLogger package package9;public class MyCustomLogger { public void info() { System.out.println("adding a and b"); } } Calculator package package9;public class Calculator { private MyCustomLogger myCustomLogger; public…… Continue reading Stubbing a non-static void method to do nothing

In this post under Mockito, I will show with example how to stub a void method to execute code other than real code. For our example, I will use the below classes MyCustomLogger package package8; public class MyCustomLogger { public void info() { System.out.println("adding a and b"); } } Calculator package package8; public class Calculator…… Continue reading Stubbing a non-static void method to do something

In this post under Mockito, I will show with example how to configure Mockito to call mock object’s real non-static non-void method instead of stubbed one. For our example, we will use below classes IndianCash package package7; public class IndianCash { public double getCash() { return 10; } } IndianCash package package7; public class IndiaToUSACashConverter…… Continue reading how to call real non-static non-void method using mock object

In this post under Mockito, I will show with example how to stub a non-static non-void method of a mock object to return a hardcoded value. For our example, we will use the below classes IndianCash package package6; public class IndianCash { public double getCash() { return 10; } } IndiaToUSACashConverter package package6; public class…… Continue reading Stubbing a non-static non-void method to return something

In this post under Mockito, I will show with example how to create mock of an interface. For our example we will use below interface DaoI package package5; public interface DaoI { public int insert(Object object); } Below is the test class where we create a mock of “DaoI” interface Test class package package5; import…… Continue reading Mocking Interface

In this post under Mockito, I will show with example how to create mock of an abstract class For our example we will use below abstract class Shape package package4; public abstract class Shape { public abstract int calculateArea(); public void display() { System.out.println("Area is:" + calculateArea()); } } Below is the test class where…… Continue reading Mocking Abstract classes

In this post under Mockito, I will show with example the purpose of “@InjectMocks” annotation. In the previous post, I showed with example, the purpose of “@Mock” annotation. For recap “@Mock” annotation is used to instruct Mockito framework to create a mock of an object and assign it to variable. We write unit test class…… Continue reading Using @InjectMocks annotation

In my previous post under Mockito, I showed you with example how to manually create a mock. In this post under Mockito, I will show with example how to tell Mockito to create a mock and assign the reference to a variable. To tell Mockito framework to create a mock of a class and assign…… Continue reading Using @Mock annotation

In this post under Mockito, I will show with example how to create a mock of a class. For our example I will use the “Calculator” class with below structure. Calculator package package1; public class Calculator { public int add(int x, int y) { return x + y; } public int multiple(int x, int y)…… Continue reading Creating a mock
