プロジェクトの歴史

The project describes its origin as a tool built to validate complex data APIs used by analytics dashboards while fitting into source control and CI/CD workflows. Its first public release, v0.1.0, shipped at the end of 2022 with basic YAML/JSON test definitions, request execution, response comparisons, tags, variables, extraction, dependencies, and iteration support.

Through 2023 and 2024, Jikken evolved from a simple runner into a broader API-testing toolkit. The changelog shows the move to command-oriented usage with `jk run` and `jk dryrun`, support for staged tests and setup/cleanup, a user-path configuration file, JUnit output, OpenAPI-based test generation, a VSCode extension, secrets, body schemas, generated test data, and formatting and validation commands.

採用の歴史

Jikken's distribution history is tied to Rust and cross-platform package channels. The project publishes to crates.io and documents installation through Cargo, Homebrew/Linuxbrew, Chocolatey, prebuilt GitHub release binaries, and source builds, which made it practical for mixed macOS, Linux, and Windows teams to add the same API-test runner to developer machines and CI agents.

使われ方

Jikken is used by writing `.jkt` files that define requests and validations, then running `jk run`, `jk dryrun`, `jk list`, `jk format`, or `jk validate`. The documented examples emphasize status-code checks, multi-stage flows, token extraction from one response into later requests, body comparison between API versions, ignored response fields, tag filtering, and recursive discovery.

パッケージ好きにとっての重要性

For package collectors, Jikken is a small example of the post-Postman CLI testing niche: API tests stored as plain files, versioned with application code, runnable without a GUI, and packaged through Rust's cargo ecosystem as well as desktop package managers. Its history also shows a common modern path for CLI tools: start with a narrow runner, then add OpenAPI generation, JUnit output, editor support, secrets, and platform binaries as automation use grows.

タイムライン

• 2022: v0.1.0 introduced the Jikken CLI, YAML/JSON test definitions, variables, comparisons, tags, and ordered test dependencies.
• 2023: v0.4.0 moved execution into explicit commands such as `jk run` and `jk dryrun`; v0.5.0 added optional telemetry and user-path configuration.
• 2024: v0.7.0 added JUnit output, OpenAPI test generation, `jk list`, and a VSCode extension for JKT files.
• 2024: v0.8.0 added secrets, body schemas, generated data for fuzz-style validation, `jk format`, and `jk validate`.
• 2026: v0.8.4 added numeric array indexing for variable extraction from root-level JSON arrays.

Related projects

• Jikken sits near GUI API clients and test tools such as Postman, Insomnia, Newman, HTTPie, and curl, but its package-manager identity is closer to Rust CLI tools that expect plain files, CI execution, and reproducible installation. Its OpenAPI generation connects it to schema-first API workflows.
