An ergonomic, opinionated framework for SQL integration test.

Example

See basic.rs to learn how to setup a basic test. This is the directory structure of examples

$ tree examples/
examples/
├── basic-case               # Testcase root directory
│   └── simple               # One environment
│       ├── config.toml      # Config file for current environment
│       ├── select.result    # Expected result file
│       └── select.sql       # Input SQL testcase
├── basic.rs                 # Entrypoint of this example

When run it via

cargo run --example basic

It will do following things:

1. Collect all environments(first-level directory) under basic-case.
2. Run testcases(.sql files) under environment one after one.
   1. Write temporary result to {testcase}.output
   2. Compare {testcase}.output with {testcase}.result using diff
3. Report result.

Our target is to keep *.result file up to date, when *.output is equals to its corresponding result, the runner will delete it after executed.

When there is any diffs, the runner will keep *.output for later investigation.

Below is the output of this example:

Run testcase...
Start, env:simple, config:Some("examples/basic-case/simple/config.toml").
Test case "examples/basic-case/simple/select" finished, cost: 0ms
Environment simple run finished, cost:1ms
Stop, env:simple.
MyDB stopped.
