HTTPBodyNotContains asserts that a specified handler returns a body that does not contain a string. For even easier Golang testing, there is a lesser known technique from the “testify” package.
NotNil (t, total, "The `total` should not be `nil`") assert. If you use testify/assert, then it's a one-liner: func TestOtherFunctionThatPanics(t *testing.T) { assert.Panics(t, OtherFunctionThatPanics, "The code did not panic") } Or, if your OtherFunctionThatPanics has a signature other than func(): In this tutorial, we’ve managed to look at how you can use assertions from the testify package to do things like assert if things are equal, or not equal or nil. I have used golang for sometime but only recently I finally understand how to do object mocking in a golang test. Testify Assertion Library: Though providing very useful and powerful native support, unfortunately golang doesn’t provide any behavioral/assertion library. Six line assert for testing without any library. This post is my self documentation of how I reached to my current understanding. GitHub Gist: instantly share code, notes, and snippets. How to assert values in golang unit tests. I am new to Golang, probably most of you guys here already figured this, obviously. A type assertion doesn’t really convert an interface to another data type, but it provides access to an interface’s concrete value, which is typically what you want.. Equal ( t , - 2 , total , "Expecting `-2`" ) } While we have the ability to write tests out of the box with Golang, if we want some useful tools such as assert , we’ll need to grab a package off the internet. go version go version go1.13.8 darwin/amd64 Does this issue reproduce with the latest release? What version of Go are you using (go version)? The type assertion x. Let’s start with an example:
QA engineers tend to use “assert” for more complex projects. r/golang: Ask questions and post articles about the Go programming language and related tools, events etc. Since I came from Java, the way of how mocking an object in golang was not really clear for me. Suppose we want to assert that mockerDoer‘s Do method will be called once, with 123 and "Hello GoMock" as arguments, and will return nil. If you have Java or .Net background, Testify will look like an old friend. To do this, we can now call EXPECT() on the mockDoer to set up its expectations in our test.The call to EXPECT()returns an object (called a mock recorder) providing methods of the same names as the real object. Golang assert. Press J to jump to the feed. If you were about to start writing tests in golang and haven’t found this awesome assertion library, testify yet, you were gonna miss a lot!
It provides assertions very similar to jUnit family together with mocking support.
