An acceptance test is a Go test function with the prefix TestAcc.
Before running: acceptance tests create real infrastructure against the
provider's live API, which may incur cost. Confirm the configured
credentials point at a test account before proceeding.
To run a focused acceptance test named TestAccFeatureHappyPath:
Run go test -run=TestAccFeatureHappyPath -timeout 60m with the
following environment variables:
TF_ACC=1
Default to non-verbose test output. Always pass an explicit -timeout:
go test kills any test run after 10 minutes by default, and acceptance
tests routinely exceed that.
The acceptance tests may require additional environment variables for
specific providers. To discover which ones:
Read the test's PreCheck / testAccPreCheck function and search the
test files: grep -rn "os.Getenv" --include="*_test.go".
Check the repository's README, CONTRIBUTING, or .env.example for
documented test setup.
The provider's Configure method shows how credentials are resolved;
use the provider-configuration skill (if available) to understand a
credential provider chain.
Set the variables for the single test invocation
(EXAMPLE_API_KEY=... TF_ACC=1 go test ...) rather than exporting them
into the shell profile, and never write secret values into files inside
the repository.
To diagnose a failing acceptance test, use these options, in order. These
options are cumulative: each option includes all the options above it.
Run the test again. Use the -count=1 option to ensure that go test does
not use a cached result.
Offer verbose go test output. Use the -v option.
Offer debug-level logging. Enable debug-level logging with the environment
variable TF_LOG=debug.
Offer to persist the acceptance test's Terraform workspace. Enable
persistence with the environment variable TF_ACC_WORKING_DIR_PERSIST=1.
A passing acceptance test may be a false negative. To "flip" a passing
acceptance test named TestAccFeatureHappyPath:
Edit the value of one of the TestCheckFuncs in one of the TestSteps in the
TestCase.
Run the acceptance test. Expect the test to fail.
If the test fails, then undo the edit and report a successful flip. Else,
keep the edit and report an unsuccessful flip.
If a test run is interrupted, real resources may be left behind; run the
provider's sweepers if it registers them (see the provider-test-patterns
skill's sweeper reference, if available). For writing or restructuring
tests, use the provider-test-patterns skill.
