+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](../highlighters/main/test-data) for examples.
+
+Tests should set the following variables:
+
+1.
+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.
+
+2. 
+If a test sets `$skip_test` to a non-empty string, the test will be skipped
+with the provided string as the reason.
+
+3. 
+If a test sets `$fail_test` to a non-empty string, the test will be skipped
+with the provided string as the reason.
+
+4.
+If a test sets `unsorted=1` the order of highlights in `$expected_region_highlight`
+need not match the order in `$region_highlight`.
+
+5.
+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:
+
+```zsh
+setopt PATH_DIRS
+mkdir -p foo/bar
+touch foo/bar/testing-issue-228
+chmod  +x foo/bar/testing-issue-228
+path+=( "$PWD"/foo )
+
+BUFFER='bar/testing-issue-228'
+
+expected_region_highlight=(
+  "1 21 command" # bar/testing-issue-228
+)
+```
+
+
+Writing new tests
+-----------------
+
+An experimental tool is available to generate test files:
+
+```zsh
+zsh -f tests/generate.zsh 'ls -x' acme newfile
+```
+
+This generates a `highlighters/acme/test-data/newfile.zsh` test file based on
+the current highlighting of the given `$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/test-highlighting.zsh) tests the correctness of
+the highlighting. Usage:
+
+```zsh
+zsh test-highlighting.zsh <HIGHLIGHTER NAME>
+```
+
+All tests may be run with
+
+```zsh
+make test
+```
+
+which will run all highlighting tests and report results in [TAP format][TAP].
+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`).
+
+[TAP]: http://testanything.org/
+
+
+Performance test
+----------------
+
+[`test-perfs.zsh`](tests/test-perfs.zsh) measures the time spent doing the
+highlighting. Usage:
+
+```zsh
+zsh test-perfs.zsh <HIGHLIGHTER NAME>
+```
+
+All tests may be run with
+
+```zsh
+make perf
+```
