• Provide a (normalised) area under curve for timeline output variables.

Variables for statistics that produce a timeline, e.g., coverage development over time imply in interesting property: while the final coverage of two distinct runs/configurations might be equal, one might have a faster coverage increase than the other, thus could be considered better. The area under curve, i.e., the integral over the development function allows to access this property easily. - Add the ability to write the logging to a log file and not only STDOUT. - Add an auto-deploy action to GitHub to push releases to PyPI. - Fix a typo in the documentation (cf.

pynguin - Pynguin 0.27.0

• Write Pynguin version number to Cobertura XML report
• Fix the computation of coverage values

Pynguin 0.26.0 added the possibility to optimise for, e.g., branch coverage while yielding the line coverage of the resulting test suite in the end. This had some unintentional implications, such as the value of the Coverage output variable having weird values. We fix this by providing additional output variables FinalBranchCoverage and FinalLineCoverage that contain the final coverage values after all generation and postprocessing. See the runtimevariable.py module for details. - Rewrite the internal type handling in Pynguin

This is a huge internal change that improves the internal type system and adds the possibility to trace types during test execution. Some highlights: - we got rid of our internal abstraction of type | None to mark whether type information exists - we allow to retrieve additional or new type information from the test execution - enhance our internal type representation to make it more flexible - add the missing primitive type complex - a more suitable subtyping check for Unions

- Python
Published by stephanlukasczyk over 3 years ago

pynguin - Pynguin 0.26.0

• Allow the calculation of coverage values regardless of optimisation.

Allows to yield, for example, the resulting line coverage of the test suite, while the optimisation during test generation was done for branch coverage. Add the required coverage values to your --output-variables list to activate this feature.

Note: when doing this, the Coverage output variable will contain the average value of the incorporated coverage values! - Provide a Cobertura-like coverage report

Pynguin already provides an HTML report that can be activated by setting --create-coverage-report True. This report is nice for human users but not very usable if one wants to automatically reason about the achieved coverage using tools. We thus also emit an XML report in the style of the Cobertura tool that can be used for further automated tools. - Fix typo on test_parameterizedstatements.py (see #27, thanks to @stavares843) - Fix typo on testcase.py (see #26, thanks to @stavares843) - Improve mutation-based assertion generation

The assertion generation now does not more compare the recorded assertion traces but actually executes the assertions to make the whole process more reliable. Besides, we do not check for is not None as a fallback for object checks any more, but use an isinstance check on the object's type to have a more precise assertion. - Make statistics tests debuggable

Some accidental circular import made it impossible to run a debugger on tests in pynguin.utils. We resolved this by moving tests to another package. - Partial rework of internal type system

We added an abstraction layer over the existing type hints from a module to make handling and reasoning with types easier. This abstraction is based on the one used by mypy, however, we only cover a small part of what PEP-484 actually defines. - Make assertion generation more strict

pynguin - Pynguin 0.23.0

• Provide a naive inheritance graph to improve input generation.
• Improve killing of long-running test-case executions
• Add computation of mutation scores for MUTATION_ANALYSIS assertion generation.

The output variables NumberOfCreatedMutants, NumberOfKilledMutants, NumberOfTimedOutMutants, and MutationScore allow to export those values. - Do not enable typing.TYPE_CHECKING for SUT analysis as this may cause circular imports. - Improve the black list of modules that shall not be incorporated into the test cluster. - Annotate failing tests with @pytest.mark.xfail(strict=True). - Improve log output of mutation-based assertion generation. - Add instrumentation to mutated modules to easier kill them.

This change is relevant only to the MUTATION_ANALYSIS assertion-generation strategy. - Write errors in execution threads to the log instead of STDERR to avoid cluttering log output. - Add limits for amount and size of constants in the constant pool.

The configuration options max_dynamic_length and max_dynamic_pool_size allow to set sizes for the maximum length of strings/bytes that shall be stored in the dynamic constant pool and the maximum numbers of constants of a type, respectively. This prevents the constant pool from growing unreasonably large. - Improve handling of type annotations. - Fix computation of cyclomatic complexity.

Computing cyclomatic complexity does not work for functions that are not present in the AST, e.g., default constructors. We now omit those from the computation of the cyclomatic-complexity output variables.

Parsing included modules raised an issue when the enum module is used: the test cluster then had a reference to the enum.Enum class, which obviously does not contain any fields. In the following, generating tests failed, as soon as this class was selected to fulfil parameter values because there was no field to select from, e.g., MyEnum.MY_FIELD. We now exclude empty enums from the test cluster.

pynguin - Pynguin 0.20.0

Breaking Changes

• Remove splitting into passing and failing test suite.

Previously, we consider a test case passing if it did not raise any exception during its execution; it was considered failing otherwise. Pynguin did a split of the test cases into two test suites before exporting them. This was mainly an artefact from implementing the random algorithm in the very beginning of the project. Due to the improved assertion export for exception assertions we can now get rid of the split and export only one test module containing all generated test cases. - Remove the option to use a log file (--log_file or --log-file).

Pynguin writes its output to STDOUT/STDERR now, if requested by the -v/-vv switch. This output is formatted by @willmcgugan's amazing rich library. A user can disable the output formatting by setting the --no-rich flag. Of course, because we believe that rich is such an awesome library, we also provide an alias for this flag, called --poor😉

Further Changes

• Distinguish between expected and unexpected exceptions.

We consider an exception to be expected if it is explicitly raised in the code under test or is documented in the code's docstring. For those exceptions we build an with pytest.raises block around the exception-raising statement. All other exceptions are considered to be unexpected. We decorate the test method with the @pytest.mark.xfail decorator and let the exception happen. It is up to the user to decide whether such an exception is expected. An exception here is the AssertionError: it is considered to be expected as soon as there is an assert statement in the code under test. - Improve installation description to explicitly point to using a virtual environment (see GitHub issue #23, thanks to @tuckcodes). - Improve variable names and exception assertions

The assertion generation got an improved handling for asserting on exceptions, which creates more meaningful and (hopefully) better understandable assertions for exceptions. - Enhance the module analysis

This is basically a rewrite of our previously existing test cluster, which keeps track of all the callables from the subject under test as well as the subject's dependencies. It also incorporates an analysis of the subject's AST (if present) and allows for more and more precise information about the subject which can then improve the quality of the generated tests. - To distinguish bytecode instructions during instrumentation we add an ArtificialInstr for our own added instructions. - Fix a bug in the tracing of runtime types.

During assertion generation Pynguin tracks the variable types to decide for which values it actually is able to generate assertions. Creating an assertion on a generator function does not work, as the type is not exposed by Python but only present during runtime—thus generating an object of this type always fail. We mitigate this by ignoring objects of type builtins.generator from the assertion generation. - Improve documentation regarding coverage measurement and the coverage report

pynguin - Pynguin 0.19.0

Breaking Change

• One can now use multiple stopping conditions at a time.

This breaks the CLI in two ways: - The parameter --stopping-condition has been removed. - The parameter --budget was renamed to --maximum-search-time.

Users have to change their run configurations accordingly!

To specify stopping conditions, add one or many from --maximum-search-time, --maximum-test-executions, --maximum-statement-executions, and --maximum-iterations to your command line.

Further Changes

• Clarify log output for search phases
• Pynguin now uses the ast.unparse function from Python's AST library instead of the third-party astor library to generate the source code of the test cases.

Fix documentation generation by adding our MutPy fork as a dependency

- Python
Published by stephanlukasczyk over 4 years ago

pynguin - Pynguin v0.13.0

• Add an assertion-generation strategy based on mutation (thanks to @f-str).

The new strategy is enabled by default (can be configured using the --assertion-generation parameter). It uses a custom fork of the mutation-testing framework MutPy, which mutates the subject under test and for each mutant traces the values of fields and returned by method calls. If these values differ between mutant and original code, an assertion is generated based on the result on the original subject under test. One can also control whether the strategy shall also generate assertions for unchanged values by the --generate-all-assertions flag.

The release also updates the documentation accordingly.

Note: This feature is an early prototype of such an assertion generation, which might cause unexpected behaviour. You can switch back to the previous strategy for assertion generation by setting --assertion-generation SIMPLE.

pynguin - Pynguin v0.12.0

• Generate more reasonable variable names in tests. Before this release, Pynguin only generated variables named var0, var1, etc. A simple heuristics now attempts to generate more reasonable names depending on the type of the variable, such as int_0, bool_1, or str_2. We also adjusted the documentation to match this change.
• We updated all provided PyCharm run configurations the use the more sophisticated queue example instead of the simple example module to see an improved output.
• Prevent a potential regression when updating the dependencies to version 0.0.17 of the simple-parsing library for CLI argument parsing, which changed its API.

• Improve documentation
• Split and extend FitnessValues to avoid expensive re-computations. This also extends the API of the FitnessValues and refactors large parts of the fitness handling.
• Fix for bumpiness of flaky tests. Whenever Pynguin generates a test that behaves flaky result could be that coverage over time looks like ventricular fibrillation especially for the MIO algorithm. The fix prevents this by carefully revisiting the equality of chromosomes.

pynguin - Pynguin v0.9.2

• Add explicit code-execution prevention (thanks to @Wooza).

Pynguin now requires you to set the PYNGUIN_DANGER_AWARE environment variable before it actually does test generation. This was added due to the fact that Pynguin executes the module under test, including its dependencies, which could potentially cause harm on the user's system. By requiring the variable to be set explicitly, a user confirms that they are aware of this issue. Inside the Docker container, the variable is set automatically; we highly recommend this way of executing Pynguin!

• Improve input generation for collection types.

• Add an implementation of tournament selection for the use with DynaMOSA, MOSA, and Whole Suite.

For Whole Suite, on can choose the selection algorithm (either rank or tournament selection) by setting the value of the --selection parameter. - Add DynaMOSA test-generation algorithm.

It can be selected via --algorithm DYNAMOSA. - Add MIO test-generation algorithm.

It can be selected via --algorithm MIO. - Add a random sampling algorithm based on test cases.

The algorithm is available by setting --algorithm RANDOM_TEST_CASE_SEARCH. It randomly picks one test case, adds all available fitness functions to it and adds it to the MOSA archive. If the test case is covering one fitness target it is retrieved by the archive. If it covers an already covered target but is shorter than the currently covering test case for that target, it replaces the latter. - Fix OSError from executors queue.

The queue was kept open until the garbage collector delete the object. This caused an OSError because it reached the OS's limit of open resource handles.
We now close the queue in the test-case executor manually to mitigate this. - Fix __eq__ and __hash__ of parameterised statements.

Before this, functions such as foo(a) and bar(a) had been considered equivalent from their equals and hash-code implementation, which only compared the parameters and returns but not the actual function's name. - Fix logging to work properly again.
