About

This package provides utilities for testing Polysemy programs:

Example

import Path (relfile)
import Polysemy.Test
import Test.Tasty (defaultMain)

test_fixture :: UnitTest
test_fixture =
  runTestAuto do
    fixContent1 <- fixtureLines fixRel
    fixPath <- Test.fixturePath fixRel
    fixContent2 <- Text.lines <$> embed (Text.readFile (toFilePath fixPath))
    fixContent1 === fixContent2
    fixContent1 === ["file", "content"]
  where
    fixRel =
      [relfile|files/file1|]

main :: IO ()
main =
  defaultMain (unitTest test_fixture)

Fixtures

Any file that is located below the subdirectory fixtures inside the test directory can be accessed using the constructors Test.fixturePath, Test.fixture and Text.fixtureLines.

You can override the path used to look for the fixtures directory by using runTest instead of runTestAuto. The latter analyzes the call stack to determine the test directory.

Temp Files

The constructors Test.tempDir, Test.tempFile, Test.tempFileContent and Test.tempFileLines allow you to create and read files in the temp directory within the test directory.

Paths

All paths are of type Path from the package path.

You can construct them using the quasiquoters reldir, absdir etc. or the functions parseRelDir, parseAbsDir etc.
