How to get the stacktrace of the err not the stack trace of the Expect

[dschveninger]

Expect(err).ShouldNot(HaveOccurred())
or
Expect(err).ToNot(HaveOccurred())

Only give you the Expect stackTrace or the stackTrace of the DSL. We are looking for the stackTrace of the error

Example output of Expect(err).ShouldNot(HaveOccurred())

When we use github.com/pkg/error
and
Expect(err).NotTo(HaveOccurred(), "Error: %+v", err)
we get a better stackTrace

Example output of Expect(err).NotTo(HaveOccurred(), "Error: %+v", err)

What is the proper way to get the Stack Trace of the error?

Code example

package ginkgo_error_test

import (
	"testing"

	. "github.com/onsi/ginkgo/v2"
	. "github.com/onsi/gomega"
	"github.com/pkg/errors"
)

//nolint:paralleltest // Not needed in Ginkgo suite setup.
func TestUserRp(t *testing.T) {
	RegisterFailHandler(Fail)
	RunSpecs(t, "Examples")
}

var _ = Describe("Stack Trace examples", Label("issues"), func() {
	Context("Standard Approach", func() {
		Context("ShouldNot", func() {
			It("One function deep", func() {
				err := FunctionOne(true, false, false)
				Expect(err).ShouldNot(HaveOccurred())
			})
			It("two function deep", func() {
				err := FunctionOne(false, true, false)
				Expect(err).ShouldNot(HaveOccurred())
			})
			It("three function deep", func() {
				err := FunctionOne(false, false, true)
				Expect(errors.Cause(err)).ShouldNot(HaveOccurred())
			})
		})
		Context("NotTo", func() {
			It("One function deep", func() {
				err := FunctionOne(true, false, false)
				Expect(err).NotTo(HaveOccurred())
			})
			It("two function deep", func() {
				err := FunctionOne(false, true, false)
				Expect(err).NotTo(HaveOccurred())
			})
			It("three function deep", func() {
				err := FunctionOne(false, false, true)
				Expect(err).NotTo(HaveOccurred())
			})
		})
	})
	// this direction will give you the stack trace of the Expect not the called function that had the error
	Context("using github.com/pkg/errors", func() {
		It("One function deep", func() {
			err := FunctionOne(true, false, false)
			Expect(err).NotTo(HaveOccurred(), "Error: %+v", err)
		})
		It("two function deep", func() {
			err := FunctionOne(false, true, false)
			Expect(err).NotTo(HaveOccurred(), "Error: %+v", err)
		})
		It("three function deep", func() {
			err := FunctionOne(false, false, true)
			Expect(err).NotTo(HaveOccurred(), "Error: %+v", err)
		})

	})
})

func FunctionOne(oneReturnError, twoReturnError, threeReturnError bool) error {
	if oneReturnError {
		return errors.New("Error cam from FunctionOne")
	}
	return FunctionTwo(twoReturnError, threeReturnError)
}

func FunctionTwo(twoReturnError, threeReturnError bool) error {
	if twoReturnError {
		return errors.New("Error cam from FunctionTwo")
	}
	return FunctionThree(threeReturnError)
}

func FunctionThree(threeReturnError bool) error {
	if threeReturnError {
		return errors.New("Error cam from FunctionThree")
	}
	return nil
}

Output from code above run

hey @dschveninger - the Ginkgo stack trace always simply points to the location of the failure. In this case an Expect(..)... is failing and Ginkgo is pointing to that failure.

It is up to the Gomega matcher to provide whatever information is necessary to adequately describe the failure to the user. In this case, since Gomega simply tells you that an error occurred. Since Go doesn't attach stack traces to errors by default there isn't anything Gomega can do out of the box to provide you with that information. (An error is just a value in Go - it doens't intrinsically contain any context about where it was generated outside of what you explicitly inject into it)

If, however, you use an error library that does provide stack traces then you have three options:

1. you can build a custom matcher that parallels HaveOccurred but emits the stack trace
2. you can wrap error objects with a struct that implements GomegaStringer to generate custom output that includes the stack trace.
3. (perhaps easiest) you can register a custom formatter that detects the special stack trace error objects and renders the stack trace for you.

Let's us try some of your suggestion. Thank you for the ideas. Once we find the best direction, we will update this issue and close it if you do not mind.
