Using bin/test.sh
bin/test.sh
(path relative to the top level repo dir) can run selected
test groups, generate coverage report, pass GHC RTS options when
running tests. test.sh
runs the tests with restricted memory, see
bin/test.sh
source for details on the amount of memory used or to change it.
To generate coverage report:
$ bin/test.sh --coverage
To view coverage report, open ./hpc_index.html
in browser.
See bin/test.sh --help
for more info.
Build a single test
$ cabal build test:Prelude.Serial
or:
$ cd test; cabal build Prelude.Serial
Build with optimizations:
$ cabal build --flag opt ...
Build all tests
$ cabal build --enable-tests all
or:
$ cd test; cabal build --enable-tests
Or this, note this command does not work as expected when in the "test" dir:
$ cabal build --enable-tests streamly-tests
Build and run
Running all test suites, use any of the following:
$ cabal test all
or:
$ cd test; cabal test
Or this, note this command does not work as expected when in the "test" dir:
$ cabal test streamly-tests
Build and Run a single test suite
To run Prelude.Serial
test-suite:
$ cabal run test:Prelude.Serial
or:
$ cd test; cabal run Prelude.Serial
Note you could use cabal test Prelude.Serial
but that unfortunately builds
all the test suites before running Prelude.Serial
.
Naming of test modules
Tests are organized by source modules. For example, for the source
module Streamly.Data.Array
and Streamly.Internal.Data.Array
we have
a test module Data.Array
. For some modules tests for a source module
are broken into multiple modules. For example, for Streamly.Prelude
we have
Streamly.Prelude.Serial
, Streamly.Prelude.Async
etc.
