bazel-bats: bazel test rules for the BATS testing framework (bats-core)

Usage

In your WORKSPACE file load and include as follows:

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

BAZEL_BATS_COMMIT_ID = "e85b43efc90133d5cd4ca807a811e9aa4006fb49"

git_repository(
    name = "bazel_bats",
    remote = "https://github.com/filmil/bazel-bats",
    commit = BAZEL_BATS_COMMIT_ID,
    shallow_since = "1677540706 -0800",
)

load("@bazel_bats//:deps.bzl", "bazel_bats_dependencies")

bazel_bats_dependencies()

You can alternatively specify the specific bats-core version, as well as optionally adding bats-core extensions.

BATS_ASSERT_VERSION = "2.0.0"
BATS_ASSERT_SHA256 = "15dbf1abb98db785323b9327c86ee2b3114541fe5aa150c410a1632ec06d9903"
BATS_CORE_VERSION = "1.7.0"
BATS_CORE_SHA256 = "ac70c2a153f108b1ac549c2eaa4154dea4a7c1cc421e3352f0ce6ea49435454e"
BATS_SUPPORT_VERSION = "0.3.0"
BATS_SUPPORT_SHA256 = "7815237aafeb42ddcc1b8c698fc5808026d33317d8701d5ec2396e9634e2918f"

# ...

bazel_bats_dependencies(
    version = BATS_CORE_VERSION,
    sha256 = BATS_CORE_SHA256,
    # Optional test extensions
    bats_assert_version = BATS_ASSERT_VERSION,
    bats_assert_sha256 = BATS_ASSERT_SHA256,
    bats_support_version = BATS_SUPPORT_VERSION,
    bats_support_sha256 = BATS_SUPPORT_SHA256
)

In your BUILD.bazel file add the following:

load("@bazel_bats//:rules.bzl", "bats_test")

bats_test(
  name = "hello_world_test",
  srcs = ["hello_world.bats"],
)

If your test would like to make use of the bats-assert extension (assert_success, assert_failure, assert_output, etc), simply add uses_bats_assert = True to your bats_test() target. This still requires adding the appropriate load statements in your test file.

Examples

This repository is an example of a repo with BATS tests. If you have bazel installed, you can try it out as follows:

git clone https://github.com/filmil/bazel-bats.git
cd bazel-bats
bazel test //...

Feel free to take a look at the WORKSPACE file to see how your workspace file should look like and at tests/BUILD.bazel to see a sample build file.

To run the integration tests, change to the integration/ directory and run,

cd integration
bazel test //...
