zsh-syntax-highlighting / tests
Utility scripts for testing zsh-syntax-highlighting highlighters.
The tests harness expects the highlighter directory to contain a test-data
directory with test data files.
See the main highlighter for examples.
Each test should define the array parameter $expected_region_highlight
.
The value of that parameter is a list of strings of the form "$i $j $style"
.
or "$i $j $style $todo"
.
Each string specifies the highlighting that $BUFFER[$i,$j]
should have;
that is, $i
and $j
specify a range, 1-indexed, inclusive of both endpoints.
If $todo
exists, the test point is marked as TODO (the failure of that test
point will not fail the test), and $todo
is used as the explanation.
Note: $region_highlight
uses the same "$i $j $style"
syntax but interprets the indexes differently.
Isolation: Each test is run in a separate subshell, so any variables, aliases, functions, etc.,
it defines will be visible to the tested code (that computes $region_highlight
), but will not affect
subsequent tests. The current working directory of tests is set to a newly-created empty directory,
which is automatically cleaned up after the test exits.
highlighting test
test-highlighting.zsh
tests the correctness of the highlighting. Usage:
zsh test-highlighting.zsh <HIGHLIGHTER NAME>
All tests may be run with
make test
which will run all highlighting tests and report results in TAP format.
performance test
test-perfs.zsh
measures the time spent doing the highlighting. Usage:
zsh test-perfs.zsh <HIGHLIGHTER NAME>
All tests may be run with
make perf
