expect() when writing your own expectations. See
vignette("custom-expectation") for details.
expect(ok, failure_message, info = NULL, srcref = NULL, trace = NULL)
Message to show if the expectation failed.
Character vector continuing additional information. Included for backward compatibility only and new expectations should not use it.
Location of the failure. Should only needed to be explicitly supplied when you need to forward a srcref captured elsewhere.
An optional backtrace created by
An expectation object. Signals the expectation condition
expect() creates and signals an expectation in one go,
exp_signal() separately signals an expectation that you
have manually created with
new_expectation(). Expectations are
signalled with the following protocol:
continue_test restart is registered. When invoked, failing
expectations are ignored and normal control flow is resumed to
run the other tests.
