Instead of storing expected values in separate files, you write `snapshot()` placeholders in assertions, then run pytest with `--inline-snapshot=review` to see what values the test produces and approve them inline. The plugin rewrites your test file with the actual values, keeping your assertions and test logic in one place.\n\nIt supports multiple comparison modes (equality, ordering, membership, indexing), can store large snapshots externally, integrates with Black formatting, and works with normal assertions like `assert 1 + 1 == 3` as well as snapshot-specific syntax. Runtime dependencies are minimal: asttokens, executing, pytest, rich, tomli, and typing-extensions. The package is actively maintained, supports Python 3.9 through 3.14, and has no known security vulnerabilities.","worth_installing":"Yes. inline-snapshot is actively maintained, has low install friction, zero known vulnerabilities, and solves a real problem for teams doing approval or golden-master testing. The inline-code-first approach is a genuine alternative to file-based snapshot tools. Install it if you want snapshot testing without managing separate snapshot files, or if you prefer reviewing and approving test changes as part of code review."},"id":"inline-snapshot","links":{"html":"https://skillfed.io/packages/inline-snapshot","md":"https://skillfed.io/packages/inline-snapshot.md","pypi":"https://pypi.org/project/inline-snapshot/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-11","license_spdx":null,"license_treatment":"permissive","name":"inline-snapshot","python_support":"supports_current","summary":"golden master/snapshot/approval testing library which puts the values right into your source code"},"popularity":{"monthly_downloads":2126963,"position":3271,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.35.4"}
