go-cmp | Package for comparing Go values in tests | Testing library

Use a anonymous structs as map value definition.

Depending on how you write your tests, you may depend on reflect.DeepEqual() and ignore the linter warning ;
the drawback is : you start depending on the inner structure of the errors you return.

In the testing code I read, and the testing code we write, we use one of the following patterns :

• most of the time, we just compare the error to nil ;
• in some cases our functions return predefined error values, and we test for these specific values :

As mentioned by @s0xzwasd the issue was disabled Go modules in Goland.

go mod tidy might be useful to clear unwanted dependencies.

In this case, the message reports that one dependency is required by separate modules:

The problem here is that you are not using modules and the Google Cloud library only supports use that way. This means you do not use go get ... at all, despite the documentation at https://cloud.google.com/logging/docs/reference/libraries#client-libraries-install-go . Instead, start by creating this go.mod file:

Here is the answer:

Since you didn't mention it above: did you instrument a Go application? The Elastic APM Go "Agent" is a package which you use to instrument your application source code. It is not an independent process, but runs within your application.

So, first (if you haven't already) instrument your application. See https://www.elastic.co/guide/en/apm/agent/go/current/getting-started.html#instrumenting-source

Here's an example web server using Echo, and the apmechov4 instrumentation module:

It's indirect in this module file, so probably not needed (not imported by your code). That's why it's unnecessary to vendor.

It's tracked because it's a dependency of your machinery dependency but actually packages you're using from machinery don't need packages from code-generator.

If you want to vendor it explicitly, you can do a blank import somewhere in your code such that
