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.
Tests should set the following variables:
Each test should define the string $BUFFER that is to be highlighted and 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.
$style is a key of $ZSH_HIGHLIGHT_STYLES.
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.
If a test sets $skip_test to a non-empty string, the test will be skipped
with the provided string as the reason.
If a test sets $fail_test to a non-empty string, the test will be skipped
with the provided string as the reason.
If a test sets unsorted=1 the order of highlights in $expected_region_highlight
need not match the order in $region_highlight.
Normally, tests fail if $expected_region_highlight and $region_highlight
have different numbers of elements. To mark this check as expected to fail,
tests may set $expected_mismatch to an explanation string (like $todo);
this is useful when the only difference between actual and expected is that actual
has some additional, superfluous elements. This check is skipped if the
$todo component is present in any regular test point.
Note: $region_highlight uses the same "$i $j $style" syntax but
interprets the indexes differently.
Note: Tests are run with setopt NOUNSET WARN_CREATE_GLOBAL, so any
variables the test creates must be declared local.
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 $region_highlight), but will not affect subsequent tests. The
current working directory of tests is set to a newly-created empty directory,
which is automatically cleaned up after the test exits. For example:
setopt PATH_DIRS
mkdir -p foo/bar
touch foo/bar/testing-issue-228
chmod +x foo/bar/testing-issue-228
path+=( "$PWD"/foo )
BUFFER='bar/testing-issue-228'
expected_region_highlight=(
"1 21 command" # bar/testing-issue-228
)
Writing new tests
An experimental tool is available to generate test files:
zsh -f tests/generate.zsh 'ls -x' acme newfile
This generates a highlighters/acme/test-data/newfile.zsh test file based on
the current highlighting of the given $BUFFER (in this case, ls -x).
This tool is experimental. Its interface may change. In particular it may
grow ways to set $PREBUFFER to inject free-form code into the generated file.
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.
By default, the results of all tests will be printed; to show only "interesting"
results (tests that failed but were expected to succeed, or vice-versa), run
make quiet-test (or make test QUIET=y).
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
