testthat unit test suites for MsBackend

This folder contains unit test suites that can be called by other packages defining MsBackend instances to ensure that they are compliant with the MsBackend definition and that they provide all necessary methods/functionality.

Different test suites are available within sub-folders of this directory, each of them having one or multiple .R files defining the unit tests. A description of the unit tests and which variables need to be defined by the calling package is provided within these.

The unit tests from one test suite can be called from within another package (in their testthat.R file) like shown in the example below that will call all unit tests from the test_MsBackend test suite/directory. This tests perform all tests on a backend class assigned to a variable be, thus developers should ensure to have create an instance of their MsBackend implementation and assign it to a variable be before the code lines below.

test_suite <- system.file("test_backends", "test_MsBackend",
    package = "Spectra")
test_dir(test_suite, stop_on_failure = TRUE)

Note that setting stop_on_failure = TRUE is required since the tests would otherwise silently fail. Alternatively, it is also possible to run single test files, e.g. the test file that checks that all spectra variables can be correctly accessed or set:

test_file(file.path(test_suite, "test_spectra_variables.R"),
    stop_on_failure = TRUE)
