A derivation trace is quite a simple data structure. We test that it behaves correctly when used to store a trace of derivations in the halfspan formalism.

This is specific to the halfspan formalism, the current and only supported formalism at the time of writing. If the formalism is deprecated these tests will need to be rewritten for the new formalism and these tests should be removed.

Instance Methods

[hide private]

setUp(self)
Hook method for setting up the test fixture before exercising it.

source code

test_create_lexical_trace(self)
Just creates a derivation trace in the simplest possible way, as if it's a lexical production.

source code

test_create_rule_trace(self)
First creates two lexical traces (as tested in test_create_lexical_trace) and then a trace for applying the application rule to them.

source code

test_multiple_source_trace(self)
Creates two derivation traces like that created in test_create_rule_trace and combines them into a single trace.

source code

test_combined_traces(self)
Does the same thing as test_multiple_source_trace, but does it by creating two DTs and adding the rules from one to the other.

Method Details

[hide private]

setUp(self)

source code

Hook method for setting up the test fixture before exercising it.

Overrides: unittest.case.TestCase.setUp: (inherited documentation)

test_create_rule_trace(self)

source code

First creates two lexical traces (as tested in test_create_lexical_trace) and then a trace for applying the application rule to them. The rule is not actually applied, we just pretend it was.
