not to_be_true == true

[jonhiggs]

I would expect each of these assertions to pass:

expect $(false) to_be_false
expect $(false) not to_be_true
expect $(true) to_be_true
expect $(true) not to_be_false

however expect $(false) not to_be_true fails.

Putting $(false) in the expectation executes the false command too early. Currently, to_be_true doesn't report on the exit status after it runs, it executes the statement as part of the check.

Try expect not_to_be_true false.

Also, there currently isn't a to_be_false. If not to_be_true isn't enough it could be added.

The main use would be something like this:

expect to_be_true stub_called aws

i.e. its original intention was as a helper for stub.sh
