assert_stderr and assert_stderr_line functions are not exported

[Shurna83]

Hello,
I am new to bats, and I am trying to create a very simple test case:

// file /ede/test/check-previous-deployments.bats
#!/usr/bin/env bats

# shellcheck disable=SC2317

setup() {
    bats_require_minimum_version 1.5.0
    bats_load_library bats-support
    bats_load_library bats-assert

    # only exports func `check_previous_deployment`, that logs to stderr if user aborts
    source "/ede/lib/check-previous-deployments.sh"
}

@test "testing bats" {
    # mocking user aborting 
    ask_yn_question() { return 1; }
    run --separate-stderr check_previous_deployment
    assert_failure 11
    assert_stderr_line --partial "[WARN] My warning message"
}

I run my test with Docker:

// file run-bats.sh
#!/bin/bash

set -eou pipefail

baseDir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
readonly baseDir

docker run -it \
	-v "$baseDir/test:/ede/test" \
	-v "$baseDir/lib:/ede/lib" \
	bats/bats:latest \
	/ede/test

Unfortunately, I am facing this error. This appears also when I try using assert_stderr.

$ ./run-bats.sh 
1..2
not ok 1 testing bats
# (in test file /ede/test/check-previous-deployment.bats, line 23)
#   `assert_stderr_line --partial "$stderr" "[WARN] My warning message" failed with status 127
# /ede/test/check-previous-deployment.bats: line 23: assert_stderr_line: command not found

Looking at the bats-assert repo, I noticed:

1. In load.bash file, there is no sourcing of assert_stderr and assert_stderr_line
2. I see tests for both assert_stderr and assert_stderr_line but don't find the functions in the src folder

I am running latest version of BATS Docker image, resulting in version

$ docker run -it bats/bats:latest --version
Bats 1.14.0

Have those methods been removed, and tests and docs are yet to be updated? Or am I missing something?

Thanks

EDIT: message typos

[Shurna83]

I managed to better isolate the error with a very minimal test.

#!/usr/bin/env bats

setup() {
    bats_require_minimum_version 1.5.0
    bats_load_library bats-support
    bats_load_library bats-assert
}

@test "minimal example" {
    run --separate-stderr bash -c "echo 'Error!' >&2 ; exit 1"
    assert_failure
    assert_stderr "Error!"
}

The error is unchanged:

not ok 3 minimal example
# (in test file /ede/test/minimal.bats, line 12)
#   `assert_stderr "Error!"' failed with status 127
# /ede/test/minimal.bats: line 12: assert_stderr: command not found

Both functions are part of existing files assert_output.bash and assert_line.bash. which version of bats-assert are you using?

[Shurna83]

I am running bats with Docker.

docker run -it -v "/tests:/my-tests" bats/bats:latest /my-tests

I see bats-assert are not installed in the Docker image? Dockerfile

[martin-schulze-vireso]

The dockerfile currently has version 2.1.0 of bats-assert.

[Shurna83]

As soon as I will get some spare time, I will manage to create a minimal repo to reproduce this issue. Thanks for your answers so far!

[martin-schulze-vireso]

I dont think there is much left to reproduce. The functions you mentioned were released in Version 2.2.0, so they are not part of the docker Images yet. You can create a pull request to update the dockerfile to the most recent version.
