This is similar to how `assert_eq!` lets you compare a value against a reference value but unlike simple string assertions, snapshot tests let you test against complex values and come with comprehensive tools to review changes. Snapshot tests are particularly useful if your reference values are very large or change often. ## Example ```rust #[test] fn test_hello_world() { insta::assert_debug_snapshot!(vec![1, 2, 3]); } ``` Curious? There is a screencast that shows the entire workflow: [watch the insta introduction screencast](https://www.youtube.com/watch?v=rCHrMqE4JOY&feature=youtu.be). Or if you're not into videos, read the [5 minute introduction](https://insta.rs/docs/quickstart/). Insta also supports inline snapshots which are stored right in your source file instead of separate files. This is accomplished by the companion [cargo-insta](https://github.com/mitsuhiko/insta/tree/master/cargo-insta) tool. ## Editor Support For looking at `.snap` files there is a [vscode extension](https://github.com/mitsuhiko/insta/tree/master/vscode-insta) which can syntax highlight snapshot files, review snapshots and more. It can be installed from the marketplace: [view on marketplace](https://marketplace.visualstudio.com/items?itemName=mitsuhiko.insta).  ## Diffing Insta uses [`similar`](https://github.com/mitsuhiko/similar) for all its diffing operations. You can use it independently of insta. You can use the [`similar-asserts`](https://github.com/mitsuhiko/similar-asserts) crate to get inline diffs for the standard `assert_eq!` macro to achieve insta like diffs for regular comparisons: ```rust use similar_asserts::assert_eq; fn main() { let reference = vec![1, 2, 3, 4]; assert_eq!(reference, (0..4).collect::<Vec<_>>()); } ``` ## Sponsor If you like the project and find it useful you can [become a sponsor](https://github.com/sponsors/mitsuhiko). ## License and Links - [Project Website](https://insta.rs/) - [Documentation](https://docs.rs/insta/) - [Issue Tracker](https://github.com/mitsuhiko/insta/issues) - License: [Apache-2.0](https://github.com/mitsuhiko/insta/blob/master/LICENSE) ", Assign "at most 3 tags" to the expected json: {"id":"8907","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
