+# CLI tests
+
+The CLI tests are focused on testing the zstd CLI.
+They are intended to be simple tests that the CLI and arguments work as advertised.
+They are not intended to test the library, only the code in `programs/`.
+The library will get incidental coverage, but if you find yourself trying to trigger a specific condition in the library, this is the wrong tool.
+
+## Test runner usage
+
+The test runner `run.py` will run tests against the in-tree build of `zstd` and `datagen` by default. Which means that `zstd` and `datagen` must be built.
+
+The `zstd` binary used can be passed with `--zstd /path/to/zstd`.
+Additionally, to run `zstd` through a tool like `valgrind` or `qemu`, set the `--exec-prefix 'valgrind -q'` flag.
+
+Similarly, the `--datagen`, and `--zstdgrep` flags can be set to specify
+the paths to their respective binaries. However, these tools do not use
+the `EXEC_PREFIX`.
+
+Each test executes in its own scratch directory under `scratch/test/name`. E.g. `scratch/basic/help.sh/`. Normally these directories are removed after the test executes. However, the `--preserve` flag will preserve these directories after execution, and save the tests exit code, stdout, and stderr in the scratch directory to `exit`, `stderr`, and `stdout` respectively. This can be useful for debugging/editing a test and updating the expected output.
+
+### Running all the tests
+
+By default the test runner `run.py` will run all the tests, and report the results.
+
+Examples:
+
+```
+./run.py
+./run.py --preserve
+./run.py --zstd ../../build/programs/zstd --datagen ../../build/tests/datagen
+```
+
+### Running specific tests
+
+A set of test names can be passed to the test runner `run.py` to only execute those tests.
+This can be useful for writing or debugging a test, especially with `--preserve`.
+
+The test name can either be the path to the test file, or the test name, which is the path relative to the test directory.
+
+Examples:
+
+```
+./run.py basic/help.sh
+./run.py --preserve basic/help.sh basic/version.sh
+./run.py --preserve --verbose basic/help.sh
+```
+
+### Updating exact output
+
+If a test is failing because a `.stderr.exact` or `.stdout.exact` no longer matches, you can re-run the tests with `--set-exact-output` and the correct output will be written.
+
+Example:
+```
+./run.py --set-exact-output
+./run.py basic/help.sh --set-exact-output
+```
+
+## Writing a test
+
+Test cases are arbitrary executables, and can be written in any language, but are generally shell scripts.
+After the script executes, the exit code, stderr, and stdout are compared against the expectations.
+
+Each test is run in a clean directory that the test can use for intermediate files. This directory will be cleaned up at the end of the test, unless `--preserve` is passed to the test runner. Additionally, the `setup` script can prepare the directory before the test runs.
+
+### Calling zstd, utilities, and environment variables
+
+The `$PATH` for tests is prepended with the `bin/` sub-directory, which contains helper scripts for ease of testing.
+The `zstd` binary will call the zstd binary specified by `run.py` with the correct `$EXEC_PREFIX`.
+Similarly, `datagen`, `unzstd`, `zstdgrep`, `zstdcat`, etc, are provided.
+
+Helper utilities like `cmp_size`, `println`, and `die` are provided here too. See their scripts for details.
+
+Common shell script libraries are provided under `common/`, with helper variables and functions. They can be sourced with `source "$COMMON/library.sh`.
+
+Lastly, environment variables are provided for testing, which can be listed when calling `run.py` with `--verbose`.
+They are generally used by the helper scripts in `bin/` to coordinate everything.
+
+### Basic test case
+
+When executing your `$TEST` executable, by default the exit code is expected to be `0`. However, you can provide an alternate expected exit code in a `$TEST.exit` file.
+
+When executing your `$TEST` executable, by default the expected stderr and stdout are empty. However, you can override the default by providing one of three files:
+
+* `$TEST.{stdout,stderr}.exact`
+* `$TEST.{stdout,stderr}.glob`
+* `$TEST.{stdout,stderr}.ignore`
+
+If you provide a `.exact` file, the output is expected to exactly match, byte-for-byte.
+
+If you provide a `.glob` file, the output is expected to match the expected file, where each line is interpreted as a glob syntax. Additionally, a line containing only `...` matches all lines until the next expected line matches.
+
+If you provide a `.ignore` file, the output is ignored.
+
+#### Passing examples
+
+All these examples pass.
+
+Exit 1, and change the expectation to be 1.
+
+```
+exit-1.sh
+---
+#!/bin/sh
+exit 1
+---
+
+exit-1.sh.exit
+---
+1
+---
+```
+
+Check the stdout output exactly matches.
+
+```
+echo.sh
+---
+#!/bin/sh
+echo "hello world"
+---
+
+echo.sh.stdout.exact
+---
+hello world
+---
+```
+
+Check the stderr output using a glob.
+
+```
+random.sh
+---
+#!/bin/sh
+head -c 10 < /dev/urandom | xxd >&2
+---
+
+random.sh.stderr.glob
+---
+00000000: * * * * *                 *
+```
+
+Multiple lines can be matched with ...
+
+```
+random-num-lines.sh
+---
+#!/bin/sh
+echo hello
+seq 0 $RANDOM
+echo world
+---
+
+random-num-lines.sh.stdout.glob
+---
+hello
+0
+...
+world
+---
+```
+
+#### Failing examples
+
+Exit code is expected to be 0, but is 1.
+
+```
+exit-1.sh
+---
+#!/bin/sh
+exit 1
+---
+```
+
+Stdout is expected to be empty, but isn't.
+
+```
+echo.sh
+---
+#!/bin/sh
+echo hello world
+```
+
+Stderr is expected to be hello but is world.
+
+```
+hello.sh
+---
+#!/bin/sh
+echo world >&2
+---
+
+hello.sh.stderr.exact
+---
+hello
+---
+```
+
+### Setup & teardown scripts
+
+Finally, test writing can be eased with setup and teardown scripts.
+Each directory in the test directory is a test-suite consisting of all tests within that directory (but not sub-directories).
+This test suite can come with 4 scripts to help test writing:
+
+* `setup_once`
+* `teardown_once`
+* `setup`
+* `teardown`
+
+The `setup_once` and `teardown_once` are run once before and after all the tests in the suite respectively.
+They operate in the scratch directory for the test suite, which is the parent directory of each scratch directory for each test case.
+They can do work that is shared between tests to improve test efficiency.
+For example, the `dictionaries/setup_once` script builds several dictionaries, for use in the `dictionaries` tests.
+
+The `setup` and `teardown` scripts run before and after each test case respectively, in the test case's scratch directory.
+These scripts can do work that is shared between test cases to make tests more succinct.
+For example, the `dictionaries/setup` script copies the dictionaries built by the `dictionaries/setup_once` script into the test's scratch directory, to make them easier to use, and make sure they aren't accidentally modified.
+
+#### Examples
+
+```
+basic/setup
+---
+#!/bin/sh
+# Create some files for testing with
+datagen > file
+datagen > file0
+datagen > file1
+---
+
+basic/test.sh
+---
+#!/bin/sh
+zstd file file0 file1
+---
+
+dictionaries/setup_once
+---
+#!/bin/sh
+set -e
+
+mkdir files/ dicts/
+for i in $(seq 10); do
+	datagen -g1000 > files/$i
+done
+
+zstd --train -r files/ -o dicts/0
+---
+
+dictionaries/setup
+---
+#!/bin/sh
+
+# Runs in the test case's scratch directory.
+# The test suite's scratch directory that
+# `setup_once` operates in is the parent directory.
+cp -r ../files ../dicts .
+---
+```
