+# TL;DR
+
+If you just want to write a simple test case, check out the file
+`writing_tests.md`.
+
+# Introduction
+
+This test suite is intended for system tests, i.e. for running a binary with
+certain parameters and comparing the output against an expected value. This is
+especially useful for a regression test suite, but can be also used for testing
+of new features where unit testing is not feasible, e.g. to test new command
+line parameters.
+
+The test suite is configured via `INI` style files using Python's builtin
+[ConfigParser](https://docs.python.org/3/library/configparser.html)
+module. Such a configuration file looks roughly like this:
+``` ini
+[DEFAULT]
+some_var: some_val
+
+[section 1]
+empty_var:
+multiline_var: this is a multiline string
+    as long as the indentation
+    is present
+# comments can be inserted
+# some_var is implicitly present in this section by the DEFAULT section
+
+[section 2]
+# set some_var for this section to something else than the default
+some_var: some_other_val
+# values from other sections can be inserted
+vars can have whitespaces: ${some_var} ${section 1: multiline var}
+multiline var: multiline variables can have
+
+    empty lines too
+```
+
+For further details concerning the syntax, please consult the official
+documentation. The `ConfigParser` module is used with the following defaults:
+- Comments are started by `#` only
+- The separator between a variable and the value is `:`
+- Multiline comments can have empty lines
+- Extended Interpolation is used (this allows to refer to other sections when
+  inserting values using the `${section:variable}` syntax)
+
+Please keep in mind that leading and trailing whitespaces are **stripped** from
+strings when extracting variable values. So this:
+
+``` ini
+some_var:     some value with whitespaces before and after    
+```
+is equivalent to this:
+``` ini
+some_var:some value with whitespaces before and after
+```
+
+The test suite itself uses the builtin `unittest` module of Python to discover
+and run the individual test cases. The test cases themselves are implemented in
+Python source files, but the required Python knowledge is minimal.
+
+## Test suite
+
+The test suite is configured via one configuration file whose location
+automatically sets the root directory of the test suite. The `unittest` module
+then recursively searches all sub-directories with a `__init__.py` file for
+files of the form `test_*.py`, which it automatically interprets as test cases
+(more about these in the next section). Python will automatically interpret each
+directory as a module and use this to format the output, e.g. the test case
+`regression/crashes/test_bug_15.py` will be interpreted as the module
+`regression.crashes.test_bug_15`. Thus one can use the directory structure to
+group test cases.
+
+The test suite's configuration file should have the following form:
+
+``` ini
+[General]
+timeout: 0.1
+
+[paths]
+binary: ../build/bin/binary
+important_file: ../conf/main.cfg
+
+[variables]
+abort_error: ERROR
+abort_exit value: 1
+```
+
+The General section only contains the `timeout` parameter, which is actually
+optional (when left out 1.0 is assumed). The timeout sets the maximum time in
+seconds for each command that is run before it is aborted. This allows for test
+driven development with tests that cause infinite loops or similar hangs in the
+test suite.
+
+The paths and variables sections define global variables for the system test
+suite, which every test case can read. Following the DRY principle, one can put
+common outputs of the tested binary in a variable, so that changing an error
+message does not result in an hour long update of the test suite. Both sections
+are merged together before being passed on to the test cases, thus they must not
+contain variables with the same name (doing so results in an error).
+
+While the values in the variables section are simply passed on to the test cases
+the paths section is special as its contents are interpreted as relative paths
+(with respect to the test suite's root) and are expanded to absolute paths
+before being passed to the test cases. This can be used to inform each test case
+about the location of a built binary or a configuration file without having to
+rely on environment variables.
+
+However, sometimes environment variables are very handy to implement variable
+paths or platform differences (like different build directories or file
+extensions). For this, the test suite supports the `ENV` and `ENV fallback`
+sections. In conjunction with the extended interpolation of the `ConfigParser`
+module, these can be quite useful. Consider the following example:
+
+``` ini
+[General]
+timeout: 0.1
+
+[ENV]
+variable_prefix: PREFIX
+file_extension: FILE_EXT
+
+[ENV fallback]
+variable_prefix: ../build
+
+[paths]
+binary: ${ENV:variable_prefix}/bin/binary${ENV:file_extension}
+important_file: ../conf/main.cfg
+
+[variables]
+abort_error: ERROR
+abort_exit value: 1
+```
+
+The `ENV` section is, similarly to the `paths` section, special insofar as the
+variables are extracted from the environment with the given name. E.g. the
+variable `file_extension` would be set to the value of the environment variable
+`FILE_EXT`. If the environment variable is not defined, then the test suite will
+look in the `ENV fallback` section for a fallback. E.g. in the above example
+`variable_prefix` has the fallback or default value of `../build` which will be
+used if the environment variable `PREFIX` is not set. If no fallback is provided
+then an empty string is used instead, which would happen to `file_extension` if
+`FILE_EXT` would be unset.
+
+This can be combined with the extended interpolation of Python's `ConfigParser`,
+which allows to include variables from arbitrary sections into other variables
+using the `${sect:var_name}` syntax. This would be expanded to the value of
+`var_name` from the section `sect`. The above example only utilizes this in the
+`paths` section, but it can also be used in the `variables` section, if that
+makes sense for the use case.
+
+Returning to the example config file, the path `binary` would be inferred in the
+following steps:
+1. extract `PREFIX` & `FILE_EXT` from the environment, if they don't exist use
+   the default values from `ENV fallback` or ""
+2. substitute the strings `${ENV:variable_prefix}` and `${ENV:file_extension}`
+3. expand the relative path to an absolute path
+
+Please note that while the `INI` file allows for variables with whitespaces or
+`-` in their names, such variables will cause errors as they are invalid
+variable names in Python.
+
+
+## Test cases
+
+The test cases are defined in Python source files utilizing the unittest module,
+thus every file must also be a valid Python file. Each file defining a test case
+must start with `test_` and have the file extension `py`. To be discovered by
+the unittest module it must reside in a directory with a (empty) `__init__.py`
+file.
+
+A test case should test one logical unit, e.g. test for regressions of a certain
+bug or check if a command line option works. Each test case can run multiple
+commands which results are compared to an expected standard output, standard
+error and return value. Should differences arise or should one of the commands
+take too long, then an error message with the exact differences is shown to the
+user.
+
+An example test case file would look like this:
+
+``` python
+# -*- coding: utf-8 -*-
+
+import system_tests
+
+
+class AnInformativeName(system_tests.Case):
+
+    filename = "invalid_input_file"
+    commands = [
+	    "{binary} -c {import_file} -i {filename}"
+	]
+    retval = ["{abort_exit_value}"]
+    stdout = ["Reading {filename}"]
+    stderr = [
+        """{abort_error}
+error in {filename}
+"""
+    ]
+```
+
+The first 6 lines are necessary boilerplate to pull in the necessary routines to
+run the actual tests (these are implemented in the module `system_tests` with
+the class `system_tests.Case` extending `unittest.TestCase`). When adding new
+tests one should choose a new class name that briefly summarizes the test. Note
+that the file name (without the extension) with the directory structure is
+interpreted as the module by Python and pre-pended to the class name when
+reporting about the tests. E.g. the file `regression/crashes/test_bug_15.py`
+with the class `OutOfBoundsRead` gets reported as
+`regression.crashes.test_bug_15.OutOfBoundsRead** already including a brief
+summary of this test.
+
+**Caution:** Always import `system_tests` in the aforementioned syntax and don't
+use `from system_tests import Case`. This will not work, as the `system_tests`
+module stores the suite's config internally which will not be available if you
+perform a `from system_tests import Case` (this causes Python to create a copy
+of the class `system_tests.Case` for your module, without reading the
+configuration file).
+
+In the following lines the lists `commands`, `retval`, `stdout` and `stderr`
+should be defined. These are lists of strings and must all have the same amount
+of elements.
+
+The test suite at first takes all these strings and substitutes all values in
+curly braces with variables either defined in this class alongside (like
+`filename` in the above example) or with the values defined in the test suite's
+configuration file. Please note that defining a variable with the same name as a
+variable in the suite's configuration file will result in an error (otherwise
+one of the variables would take precedence leading to unexpected results). The
+substitution of values in performed using Python's string `format()` method and
+more elaborate format strings can be used when necessary.
+
+In the above example the command would thus expand to:
+``` shell
+/path/to/the/dir/build/bin/binary -c /path/to/the/dir/conf/main.cfg -i invalid_input_file
+```
+and similarly for `stdout` and `stderr`.
+
+Once the substitution is performed, each command is run using Python's
+`subprocess` module, its output is compared to the values in `stdout` and
+`stderr` and its return value to `retval`. Please note that for portability
+reasons the subprocess module is run with `shell=False`, thus shell expansions
+or pipes will not work.
+
+As the test cases are implemented in Python, one can take full advantage of
+Python for the construction of the necessary lists. For example when 10 commands
+should be run and all return 0, one can write `retval = 10 * [0]` instead of
+writing 0 ten times. The same is of course possible for strings.
+
+There are however some peculiarities with multiline strings in Python. Normal
+strings start and end with a single `"` but multiline strings start with three
+`"`. Also, while the variable names must be indented, new lines in multiline
+strings must not or additional whitespaces will be added. E.g.:
+
+``` python
+    stderr = [
+        """something
+        else"""
+    ]
+```
+will actually result in the string:
+
+```
+something
+        else
+```
+and not:
+```
+something
+else
+```
+as the indentation might have suggested.
+
+Also note that in this example the string will not be terminated with a newline
+character. To achieve that put the `"""` on the following line.
+
+
+## Advanced test cases
+
+This section describes more advanced features that are probably not necessary
+the "standard" usage of the test suite.
+
+
+### Creating file copies
+
+For tests that modify their input file it is useful to run these with a
+disposable copy of the input file and not with the original. For this purpose
+the test suite features a decorator which creates a copy of the supplied files
+and deletes the copies after the test ran.
+
+Example:
+``` python
+# -*- coding: utf-8 -*-
+
+import system_tests
+
+
+@system_tests.CopyFiles("{filename}", "{some_path}/another_file.txt")
+class AnInformativeName(system_tests.Case):
+
+    filename = "invalid_input_file"
+    commands = [
+	    "{binary} -c {import_file} -i {filename}"
+	]
+    retval = ["{abort_exit_value}"]
+    stdout = ["Reading {filename}"]
+    stderr = [
+        """{abort_error}
+error in {filename}
+"""
+    ]
+```
+
+In this example, the test suite would automatically create a copy of the files
+`invalid_input_file` and `{some_path}/another_file.txt` (`some_path` would be of
+course expanded too) named `invalid_input_file_copy` and
+`{some_path}/another_file_copy.txt`. After the test ran, the copies are
+deleted. Please note that variable expansion in the filenames is possible.
+
+
+### Customizing the output check
+
+Some tests do not require a "brute-force" comparison of the whole output of a
+program but only a very simple check (e.g. that a string is present). For these
+cases, one can customize how stdout and stderr checked for errors.
+
+The `system_tests.Case` class has two public functions for the check of stdout &
+stderr: `compare_stdout` & `compare_stderr`. They have the following interface:
+``` python
+compare_stdout(self, i, command, got_stdout, expected_stdout)
+compare_stderr(self, i, command, got_stderr, expected_stderr)
+```
+with the parameters:
+- i: index of the command in the `commands` list
+- command: a string of the actually invoked command
+- got_stdout/stderr: the obtained stdout, post-processed depending on the
+  platform so that lines always end with `\n`
+- expected_stdout/stderr: the expected output extracted from
+  `self.stdout`/`self.stderr`
+
+These functions can be overridden in child classes to perform custom checks (or
+to omit them completely, too). Please however note, that it is not possible to
+customize how the return value is checked. This is indented, as the return value
+is often used by the OS to indicate segfaults and ignoring it (in combination
+with flawed checks of the output) could lead to crashes not being noticed.
+
+
+### Manually expanding variables in strings
+
+In case completely custom checks have to be run but one still wants to access
+the variables from the test suite, the class `system_test.Case` provides the
+function `expand_variables(self, string)`. It performs the previously described
+variable substitution using the test suite's configuration file.
+
+Unfortunately, it has to run in a class member function. The `setUp()` function
+can be used for this, as it is run before each test. For example like this:
+``` python
+class SomeName(system_tests.Case):
+
+	def setUp(self):
+		self.commands = [self.expand_variables("{some_var}/foo.txt")]
+		self.stderr = [""]
+		self.stdout = [self.expand_variables("{success_message}")]
+		self.retval = [0]
+```
+
+This example will work, as the test runner reads the data for `commands`,
+`stderr`, `stdout` and `retval` from the class instance. What however will not
+work is creating a new member in `setUp()` and trying to use it as a variable
+for expansion, like this:
+``` python
+class SomeName(system_tests.Case):
+
+	def setUp(self):
+		self.new_var = "foo"
+		self.another_string = self.expand_variables("{new_var}")
+```
+
+This example fails in `self.expand_variables` because the expansion uses only
+static class members (which `new_var` is not). Also, if you modify a static
+class member in `setUp()` the changed version will **not** be used for variable
+expansion, as the variables are saved in a new dictionary **before** `setUp()`
+runs. Thus this:
+``` python
+class SomeName(system_tests.Case):
+
+	new_var = "foo"
+
+	def setUp(self):
+		self.new_var = "bar"
+		self.another_string = self.expand_variables("{new_var}")
+```
+
+will result in `another_string` being "foo" and not "bar".
+
+
+### Possible pitfalls
+
+- Do not provide a custom `setUpClass()` function for the test
+  cases. `setUpClass()` is used by `system_tests.Case` to store the variables
+  for expansion.
+
+- Keep in mind that the variable expansion uses Python's `format()`
+  function. This can make it more cumbersome to include formatted strings into
+  variables like `commands` which will likely contain other variables from the
+  test suite. E.g.: `commands = ["{binary} {:s}".format(f) for f in files]` will
+  not work as `format()` will expect a value for binary. This can be worked
+  around using either the old Python formatting via `%` or by formatting first
+  and then concatenating the problematic parts.
+
+
+## Running the test suite
+
+The test suite is written for Python 3 but is in principle also compatible with
+Python 2, albeit it is not regularly tested, so its functionality is not
+guaranteed with Python 2.
+
+Then navigate to the `tests/` subdirectory and run:
+``` shell
+python3 runner.py
+```
+
+The runner script also supports the optional arguments `--config_file` which
+allows to provide a different test suite configuration file than the default
+`suite.conf`. It also forwards the verbosity setting via the `-v`/`--verbose`
+flags to Python's unittest module.

+## Writing new tests
+
+The test suite is intended to run a binary and compare its standard output,
+standard error and return value against provided values. This is implemented
+using Python's `unittest` module and thus all test files are Python files.
+
+The simplest test has the following structure:
+``` python
+# -*- coding: utf-8 -*-
+
+import system_tests
+
+
+class GoodTestName(system_tests.Case):
+
+    filename = "{data_path}/test_file"
+    commands = ["{exiv2} " + filename, "{exiv2} " + filename + '_2']
+    stdout = [""] * 2
+    stderr = ["""{exiv2_exception_msg} """ + filename + """:
+{error_58_message}
+"""] * 2
+    retval = [1] * 2
+```
+
+The test suite will run the provided commands in `commands` and compare them to
+the output in `stdout` and `stderr` and it will compare the return values.
+
+The strings in curly braces are variables either defined in this test's class or
+are taken from the suite's configuration file (see `doc.md` for a complete
+explanation).
+
+When creating new tests, follow roughly these steps:
+
+1. Choose an appropriate subdirectory where the test belongs. If none fits
+   create a new one and put an empty `__init__.py` file there.
+
+2. Create a new file with a name matching `test_*.py`. Copy the class definition
+   from the above example and choose an appropriate class name.
+
+3. Run the test suite via `python3 runner.py` and ensure that your test case is
+   actually run! Either run the suite with the `-v` option which will output all
+   test cases that were run or simply add an error and check if errors occur.
