The Go Playground is a web service that runs on golang.org's servers. Package testing provides support for automated testing of Go packages. It is intended to be used in concert with the “go test” command, which automates execution of any function of the form func TestXxx(*testing.T) where Xxx does not start with a lowercase letter. Using Go Modules. This function is the entry point for execution. With it, you can build a testing suite as a struct, build setup/teardown methods and testing methods on your struct, and run them with 'go test' as per normal. Put the file in the same package as the one being tested. Godoc examples are snippets of Go code that are displayed as package documentation and that are verified by running them as tests. And the nested package can import just like the root package. Because building a single package, like with go build or go test, can easily tell when something is missing and needs to be added, but not when something can safely be removed.
Testable Examples in Go. Packages to use for Unit Testing in Go. // the rest of test} Golang assert. The require package provides same global functions as the assert package, but instead of returning a boolean result they terminate current test.. See t.FailNow for details.. mock package. Package parse provides support for parsing benchmark results as generated by 'go test -bench'. main function and main package. internal/triegen Package triegen implements a code generator for a trie for associating unsigned integer values with … They can also be run by a user visiting the godoc web page for the package … testing — This is an in-built Golang package which is used to implement and run unit/automated test cases. For example: import "math/cmplx" Here, the math package is the main package and cmplx package is the nested package. The file will be excluded from regular package builds but will be included when the “go test” command is run. If the program contains tests or examples and no main function, the service runs the tests. To write a new test suite, create a file whose name ends _test.go that contains the TestXxx functions as described here. If invoked with the -bench or -v flag, go test prints the full output even for passing package tests, in order to display the requested benchmark results or verbose logging.
5. go-cmp: package for comparing Go values in tests; License. Nested Packages: In Go language, you are allowed to create a package inside another package simply by creating a subdirectory. This allows them to write shorter test cases, and retrieve the same accurate results as provided by unit tests in Golang. Andrew Gerrand 7 May 2015 Introduction. The function name serves to identify the test routine. Removing a dependency can only be done after checking all packages in a module, and all possible build tag combinations for those packages. The main function should reside in the main package. go-testdeep is released under the BSD-style license found in the LICENSE file in the root directory of this source tree.

An example suite is shown below:
The suite package provides functionality that you might be used to from more common object oriented languages. If a package test fails, go test prints the full test output. Package list mode is when go test is called with package/path arguments, such as go test users or go test ./testFiles/. require package. To write a new test suite, create a file whose name ends _test.go that contains the TestXxx functions as described here.
