Using the Testify toolkit
Programming is not always a straightforward process. Especially, when you need to add a small piece of code to an application and ensure that the whole application works as intended. In this case, testing can help you to maintain code quality and improve its reliability.
IntelliJ IDEA supports the Testify toolkit. Testify provides several packages to work with assertions, mock objects, and testing suites. With Testify, you can run your suites and methods as regular test functions. For more information about the toolkit, refer to the description of Testify on GitHub.
Run tests with Testify
go get -u github.com/stretchr/testifyin the terminal. Alternatively, use the intention action Alt+Enter to download and install the toolkit.
Click the Run test icon and select Run <configuration>.
