Similar to testing an HTTP handler with the httptest package, we can also test HTTP outbound either with httptest or by extending the http.RoundTripper package. This article will demonstrate how to test HTTP outbound in Go. Prepare the Playground To ensure we’re on the same page, let’s clone this repository to use as our base code....

However, testing goroutines can be challenging because they execute in a random order. Sometimes, the test may finish before the goroutine completes, causing the test to fail intermittently. In this article, we’ll explore how to test goroutines in Go using just the standard library. Let’s consider this simple example:...
