Simplify test coverage scripts

[vprithvi]

We moved to Go 1.10 in #792, in which go test coverpkg has been enhanced to accept multiple packages.

The go test -coverpkg flag now interprets its argument as a comma-separated list of patterns to match against the dependencies of each test, not as a list of packages to load anew. For example, go test -coverpkg=all is now a meaningful way to run a test with coverage enabled for the test package and all its dependencies. Also, the go test -coverprofile option is now supported when running multiple tests.

This means that we can simplify the logic in cover.sh and potentially make the build faster.

[yurishkuro]

I did a test run, go test ./... ran for 58 second, make test ran for 67 seconds. Not a significant difference. To use the combined test run we would need to refactor how code coverage is generated, i.e. remove the packages with .nocover from the coverage output (or get rid of .nocover completely since we have relaxed 100% coverage rules and can probably tolerate some uncovered packages).

[yurishkuro]

Another alternative by @bogdandrutu (open-telemetry/opentelemetry-collector#671 (comment)) is to use https://github.com/ory/go-acc, which also allows cross-package coverage to be included.

[PankhudiB]

shall I use go-acc and add make task ? or is someone else working on this ?
I quite didnt understand what needs to be ignored while calculating coverage .

[PankhudiB]

This is the output of go-acc command i just ran on the repo:

[yurishkuro]

I don't think go-acc is going to be particularly useful, since it doesn't allow any more customizability than plain go test.

We want to exclude all auto-generated packages (see ALL_SRC in Makefile), and packages with .nocover files. However, those packages probably won't have any _test files and go test will not generate coverage for them, which is what we want. So this may be as simple as just switching to go test ./... and removing cover.sh.

But then if we just use go test -cover ./... we would still need script to take the output and check if it meets threshold.

[yurishkuro]

Threshold is checked when the results are submitted to codecov.io

Okay. Help me understand one more thing. Regarding the auto-generated packages that you referred earlier. Do we know what is the list of those auto-generated packages beforehand ?

In that case we can simply do something like :
EXCLUDE_PACKAGES=$(cat .file_that_has_list_of_packages_to_be_exchluded | tr '\n' '|')
go test -covermode=set -coverprofile cover.out go list ./... | grep -Ev ${EXCLUDE_PACKAGES}

[yurishkuro]

I don't think generated packages are going to be a problem for code coverage, because they do not include any _test files, which makes go test not report any coverage for them (i.e. NULL instead of 0), and thus they do not affect the total score. If you look at the current setup, we are not excluding them

./scripts/cover.sh $(shell go list ./...)

(but we do exclude them from linters)

[PankhudiB]

wanted to do a sanity before pushing.
while running the make cover command.. the test run successfully but i am getting error.
are there any prerequisites i need in my local

[yurishkuro]

CONTRIBUTING.md should describe the required setup steps. Please post the error.

yeah, this test is know to be unstable, there's an open ticket for it #1314. If you rerun the tests it usually passes.
