Include testing framework in git repo?
I'm slowly making git and unit testing parts of my regular workflow. I'd appreciate advice on whether unit testing frameworks (not the tests themselves, but the actual framework) should be included in a project's git repo.
On the one hand, it seems like it should not, as frameworks are a) readily available elsewhere and b)not unique to a project (I'm talking about popular frameworks such as qunit for JS or simpletest in PHP). In that case, perhaps a simple readme in the repo indicating the version of the framework and where to get it would suffic开发者_StackOverflowe.
On the other hand, the tests ARE part of the project (and part of the repo), and do need the framework to run, so for the sake of completeness, perhaps the framework should be included as well?
Thanks.
I almost always include the framework (a sane one should be a few libraries and executables, so not that large) - the source and tests are versioned, and If I ever go back and get version 1.2 of my code from 2001, I want the tests to run when I make that hotfix - not to fail because I'm using the test framework that I changed to in 2006.
Without the test framework in source control, I add one more thing I have to match versions of. Heck, I'd version the compiler and language libraries in there as well if it were feasible.
If you have a giant test tool/platform that can't easily be put in alongside (or can't legally be put in alongside), make sure you include a doc of some sort that tells what tool, what version, and possibly how to get it alongside the tests.
Reading the answers to this question is interesting, as it shows a very broad range of interpretations of many different aspects of software development. I am normally of the belief that dependencies of any kind should not be stored in the VCS (by VCS, I refer to tools like git, hg, svn, cvs, and not larger systems that incorporate such tools, like Xcode) because that is not the job of the VCS. Dependency tracking is best left to a packaging tool. (It seems that many people use the VCS as a primitive packaging tool, which IMHO is a huge mistake.)
I think you need to clarify what you mean by 'test framework'. For me, most of my test suites are invoked by the framework provided by automake. I certainly do not include automake in my git repository, but there is no issue with version differences in the future because all of the test framework generated by automake is included in the distribution tarball. So really the question is pushed back one more level. If you are using only a VCS to track your releases, then you have a problem because you really do need to have the test framework available when you check out an old version of the project. If the VCS is the only storage mechanism for retrieving old releases (ie, you aren't using any sort archiving of releases in tarballs), then it seems you are forced to put the framework in the VCS. But putting external software in your VCS is, frankly, stupid. The only reason to do that is if you are using the VCS as your distribution tool. So I suppose my answer is: don't put the framework in your VCS, but do put the framework in your distributions. If your VCS is your distribution tool, then there is no proper way to deal with the test framework.
Interesting question. I don't think the testing framework should be included in an application repository though.
Name the prerequisites of your project in a readme file. If you have multiple projects that use the same testing framework, you have the framework installed already and you probably don't want to download or install it again for each project.
I include NUnit DLLs in all my repositories with unit tests. I actually include everything in the repository that I need to compile and run tests. Of course, this is not feasible for some projects, but when it is feasible, it becomes extremely easy to just check out the repository and start working. No setup required.
We add all referenced libraries to our repositories.
This has the advantage that you have all required components in one place. If you have a new computer, you simply have to install you IDE of you choice, check-out the repository and you are ready.
This also makes it easy to spin up a build process on a build server, as you only have to point it to your repository, which includes everything needed for a build (despite of the .NET framework). Therefore it is easy to create a build of an older version without any version issues.
I would say no, because they are readily available elsewhere, and any experienced developer should already have those libraries readily available.
Also, some modern IDE's (eclipse in particular) already ship with the unit testing libraries you need, so it isn't critical to ship those with your source.
No, you shouldn't include outside frameworks in your repo, unless you're actually modifying the frameworks to work with your project.
Depending on what language you're using, you might want to use a README file or rely on your packaging tools; for example, both Python's distutils and Perl's Module::Build allow for specifying what external modules are required for running your tests, and will install the dependencies for your users.
From a Python world, I'd include the dependencies in my setup.py
file. Developers can fetch them then.
With tarballs, I sometimes include a generated test file so that people can atleast do some sanity tests before running the project.
