Capturing multiple method arguments (using ArgumentCaptor) passed to a method in a consecutive call
This post explains how to capture multiple arguments passed to a method in a consecutive calls. Consider the below code Class2 package package10; public class Class2 { private int val; public void method2(int val) { this.val = val; } } Class1 package package10; public class Class1 { private Class2 class2; public void method1(int val) {…… Continue reading Capturing multiple method arguments (using ArgumentCaptor) passed to a method in a consecutive call
Using ArgumentCaptor class
This post explains how to capture arguments passed to mocked methods when testing. Suppose we have classes as shown below class Class1 { private Class2 class2; public void method1(int val) { val = val * val; class2.method2(val); } } class Class2 { private int val; public void method2(int val) { this.val = val; } }…… Continue reading Using ArgumentCaptor class
How to call real method using mock object
