1import (2func TestDoAndReturn(t *testing.T) {3 ctrl := gomock.NewController(t)4 defer ctrl.Finish()5 mock := NewMockDoAndReturn(ctrl)6 mock.EXPECT().DoAndReturn(1, 2).DoAndReturn(func(x, y int) int {7 })8 fmt.Println(mock.DoAndReturn(1, 2))9}10This is a very useful feature of gomock. You can do some setup, call the function and then verify the result. You can also use gomock.Any() in place of 1 and 2. gomock.Any() is a special value which matches any value. So, you can write the above code as:11mock.EXPECT().DoAndReturn(gomock.Any(), gomock.Any()).DoAndReturn(func(x, y int) int {12 })

When most firms employed a waterfall development model, it was widely joked about in the industry that Google kept its products in beta forever. Google has been a pioneer in making the case for in-production testing. Traditionally, before a build could go live, a tester was responsible for testing all scenarios, both defined and extempore, in a testing environment. However, this concept is evolving on multiple fronts today. For example, the tester is no longer testing alone. Developers, designers, build engineers, other stakeholders, and end users, both inside and outside the product team, are testing the product and providing feedback.
There are many debates going on whether testers should know programming languages or not. Everyone has his own way of backing the statement. But when I went on a deep research into it, I figured out that no matter what, along with soft skills, testers must know some programming languages as well. Especially those that are popular in running automation tests.
When it comes to web automation testing, there are a number of frameworks like Selenium, Cypress, PlayWright, Puppeteer, etc., that make it to the ‘preferred list’ of frameworks. The choice of test automation framework depends on a range of parameters like type, complexity, scale, along with the framework expertise available within the team. However, it’s no surprise that Selenium is still the most preferred framework among developers and QAs.
JUnit is one of the most popular unit testing frameworks in the Java ecosystem. The JUnit 5 version (also known as Jupiter) contains many exciting innovations, including support for new features in Java 8 and above. However, many developers still prefer to use the JUnit 4 framework since certain features like parallel execution with JUnit 5 are still in the experimental phase.
