▸case-08 When testing a CLI tool written in Bash, we want to verify that error messages sent to standard error match `Error: Missing required config` while suppressing standard output. I usually just redirect stderr to a temporary file manually inside the test function. What is the standard pattern for asserting on command output? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-09 My shell script creates temporary files in `/tmp/test-run` during execution. Developers often manually delete files inside the test body right after the assertion, but if an assertion fails early, leftover files pollute subsequent test runs. What structural pattern prevents test pollution on failure? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-11 We are starting a test suite for a legacy system script `process_data.sh`. It might run on macOS zsh, Ubuntu bash 5.1, or Alpine busybox ash. Instead of assuming bash 4+, what step must be performed before defining tests for this script? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-21 When testing `deploy.sh --dry-run`, we need to verify that it completes successfully with exit status 0 and outputs `Dry run complete`. What assertions should be placed in the test block? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-17 We need to separate stdout from stderr assertions when testing `validator.sh`. By default, `run` captures merged output into `$output`. How can stderr be validated independently when testing error paths? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-10 Multiple tests in our test file require a mock configuration file placed at `/tmp/config.json` before executing any script commands. Instead of duplicating file creation in every test block, what pattern should be used to prepare test fixtures? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-19 We are using TDD to develop a new CLI utility `calc.sh`. We want to write a failing test for flag `--verbose` before writing any implementation code. What is the step-by-step workflow for writing the test first? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-06 We want to automate code formatting for all shell scripts in our repository using shfmt to enforce 2-space indentation and binary operator padding. How can we configure shfmt and run it as a pre-commit hook? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-20 Some unit tests for `docker_build.sh` require docker daemon access. On developer machines without docker running, these tests crash with errors instead of skipping cleanly. What mechanism should be used to skip tests conditionally when prerequisites are missing? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-07 I am writing an automated test for a script `/usr/local/bin/backup.sh` that should fail with exit code 2 when invoked without arguments. A common shortcut is checking `$?` immediately after running the script inline. How should the test be structured to reliably verify this non-zero exit status? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-01 I have a Bash script that handles user provisioning on Linux servers, and I want to start writing unit tests for it using Bats. Can you walk me through setting up the test suite? I need to verify command exit status, capture standard output, handle mock fixtures, and safely clean up resources after each test run. | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-12 We have written tests in `test/suite.bats` and verified them locally. Now we want to run this test suite automatically on every pull request in GitHub Actions. Should we run the script directly with bash, or how should automated execution be set up in CI? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-14 A script `archive_logs.sh` is supposed to compress `/var/log/app.log` into `/var/log/app.tar.gz` and remove the original log file. What is the proper pattern for testing these filesystem side effects without modifying actual host system files? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-18 We have 40 shell scripts in a repository and no existing test folder. What folder layout and file naming conventions should be established when adding unit tests? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-02 We need to automate testing for our core deployment shell script in our CI pipeline using Bats. Please provide a clear strategy and code structure for our test suite that covers verifying exit codes, inspecting filesystem side effects, and setting up isolated test environments. | pass→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-16 Our shell script calls `curl` to fetch user data. In our unit tests, we want to prevent real network calls by providing a stubbed version of `curl` that returns dummy JSON. How should external command mocks be injected into the executable PATH during tests? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-03 I'm practicing test-driven development to build a shell utility that parses configuration files. What is the recommended approach for writing Bats tests that validate parameter edge cases, check error messaging on stderr, and utilize shared test helper functions? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-05 Our application consists of microservices running on a Kubernetes cluster. We need to write end-to-end integration tests that deploy Helm charts and verify pod HTTP endpoints across nodes. How should we structure these end-to-end cluster integration tests? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-04 We have a large collection of Bash scripts in our repository and want to enforce static analysis rules to catch syntax errors, unquoted variables, and deprecated syntax before merging. How should we set up ShellCheck in our GitHub Actions workflow? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-13 Our test suite across five test files duplicates helper code for creating mock HTTP responses and verifying JSON output. What is the standard pattern for loading shared helper functions into test files? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-15 The script `db_connect.sh` relies on `DATABASE_URL`. In our tests, setting `export DATABASE_URL=postgres://localhost` directly inside one test function causes other tests to inherit that environment variable unexpectedly. How should environment variables be isolated across tests? | fail→fail | — | — | — | — | — | — | — | — | — | — | — | — |
▸case-22 We need comprehensive, production-grade test suite patterns for complex shell script mocking, fixture management, and CI matrix testing. What resource should be consulted for detailed implementation examples? | fail→pass | — | — | — | — | — | — | — | — | — | — | — | — |
