Lucas Bajolet	5ff0f146c6	packer_test: introduce global compilation queue Compiling plugins was originally intended to be an idempotent operation. This however starts to change as we introduce build customisations, which have the unfortunate side-effect of changing the state of the plugin directory, leading to conflicts between concurrent compilation jobs. Therefore to mitigate this problem, this commit changes how compilation jobs are processed, by introducing a global compilation queue, and processing plugins' compilation one-by-one from this queue. This however makes such requests asynchronous, so test suites that require plugins to be compiled will now have to wait on their completion before they can start their tests. To this effect, we introduce one more convenience function that processes those errors, and automatically fails the test should one compilation job fail for any reason.	1 year ago
Lucas Bajolet	b6b0a081ad	packer_test: add build customisation capabilities When building a plugin, we may want some customisation capabilities beyond changing the version/pre-release/metadata, and instead run commands or change files on the filesystem. To do so, we introduce functions under the BuildCustomisation type, which have two responsabilities: changing the current state of the plugin's directory, and cleaning up afterwards. These customisations are passed as parameters to the BuildSimplePlugin function, and are called one-by-one, deferring their cleanup after the build process is finished. A first implementation of such a customisation is added with this commit, in order to change the version of a module that the plugin depends on, which we'll use to change the version of the plugin SDK in order to test how Packer behaves with different versions of the SDK for a single plugin.	1 year ago
Lucas Bajolet	3c449430e1	packer_test: make PluginTestDir a structure In order for the creation of a temporary directory to install plugins into to be simpler to understand and use, we change how the directory is created, cleaned-up, and installs plugins into. Now, instead of a tuple of a string (path) and a cleanup function, we return a structure that comprises the test suite, and the temporary directory, along with methods to handle those steps independently.	1 year ago
Lucas Bajolet	31b6109430	packer_test: hide run and introduce Output When using a PackerCommand, the Run function was made public as a way to access the contents of an execution. This was clumsy as it had too many responsabilities, and was not needed strictly as Assert was performing the executions, as many times as required. This could introduce cases in which one run as spent by the caller, then the remainder were executed through Assert. Therefore, we change this convention. Now, run is private to the type, and only through Assert can a command be executed. If a test needs access to a command's output, stderr, or error, it can do so through the Output function, which requires Assert to be called first.	1 year ago
Lucas Bajolet	35b2317ef3	packer_test: rename/split lib into common/check The lib name for the common components for writing packer_test suites was not clear, and did not follow the convention established in Packer core and plugins. Therefore this commit does two things: first the lib is renamed into common as to follow this convention, and clearly document which components are common to all tests. Also checkers are placed in a subpackage of common, common/check, so that it is clearer what is meant to be used as checks for a command's execution status after it's been run, as part of Assert.	1 year ago
