# Miller regression tests
|
|
|
|
There are a few files unit-tested with Go's `testing` package -- a few dozen cases total.
|
|
|
|
The vast majority of Miller tests, though -- thousands of cases -- are tested by running scripted invocations of `mlr` with various flags and inputs, comparing against expected output, and checking the exit code back to the shell.
|
|
|
|
## How to run the regression tests, in brief
|
|
|
|
*Note: while this `README.md` file is within the `test/` subdirectory, all paths in this file are written from the perspective of the user being cd'ed into the repository base directory, i.e. this directory's parent directory.*
|
|
|
|
* `mlr regtest --help`
|
|
|
|
* `go test` -- TODO -- also comment
|
|
|
|
## Items for the duration of the Go port
|
|
|
|
* `mlr regtest -c ...` runs the C version of Miller from the local checkout
|
