When you create a mock object
mockResponse = mock(HttpServletResponse.class);
by default, all its methods that have a reference type return type (minus a few special cases) return null
.
So the return value of getOutputStream()
in this snippet
ServletOutputStream outputStream = response.getOutputStream();
is null
.
You need to set expectations and specify a return value.
when(mockResponse.getOutputStream().thenReturn(/* the value to return when that method is invoked */);
This is called stubbing.

JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
Hey LambdaTesters! We’ve got something special for you this week. ????
Selenium, a project hosted by the Apache Software Foundation, is an umbrella open-source project comprising a variety of tools and libraries for test automation. Selenium automation framework enables QA engineers to perform automated web application testing using popular programming languages like Python, Java, JavaScript, C#, Ruby, and PHP.
Nowadays, automation is becoming integral to the overall quality of the products being developed. Especially for mobile applications, it’s even more important to implement automation robustly.
Learn to execute automation testing from scratch with LambdaTest Learning Hub. Right from setting up the prerequisites to run your first automation test, to following best practices and diving deeper into advanced test scenarios. LambdaTest Learning Hubs compile a list of step-by-step guides to help you be proficient with different test automation frameworks i.e. Selenium, Cypress, TestNG etc.
