Defines 2 classes


Class: post_statement_test  - X-Ref

Unit tests for xAPI statement processing webservice.

setupBeforeClass()   X-Ref
Setup to ensure that fixtures are loaded.


setUp()   X-Ref
Setup test.


get_extenal_class()   X-Ref
Return a xAPI external webservice class to operate.

The test needs to fake a component in order to test without
using a real one. This way if in the future any component
implement it's xAPI handler this test will continue working.

return: post_statement the external class

Class: extends  - X-Ref

validate_component(string $component)   X-Ref
No description

post_statements_data(string $component, $data, array $expected)   X-Ref
This function do all checks from a standard post_statements request.

The reason for this function is because statements crafting (special in error
scenarios) is complicated to do via data providers because every test need a specific
testing conditions. For this reason alls tests creates a scenario and then uses this
function to check the results.

param: string $component component name
param: mixed $data data to encode and send to post_statement
param: array $expected expected results (i empty an exception is expected)

get_valid_statement(array $items = [])   X-Ref
Return a valid statement object with the params passed.

All tests are based on craft different types os statements. This function
is made to provent redundant code on the test.

param: array $items array of overriden statement items (default [])
return: statement the resulting statement

test_component_names(string $component, array $expected)   X-Ref
Testing different component names on valid statements.

param: string $component component name
param: array $expected expected results

components_provider()   X-Ref
Data provider for the test_component_names tests.

return: array

test_invalid_json(string $json)   X-Ref
Testing raw JSON encoding.

This test is used for wrong json format and empty structures.

param: string $json json string to send

invalid_json_provider()   X-Ref
Data provider for the test_components tests.

return: array

test_statements_agent(bool $multiple, bool $validactor, bool $validverb, array $expected)   X-Ref
Testing agent (user) statements.

This function test several scenarios using different combinations
of statement rejection motives. Some motives produces a full batch
rejection (exception) and other can leed to indivual rejection on
each statement. For example,try to post a statement without $USER
in it produces a full batch rejection, while using an invalid
verb on one statement just reject that specific statement
That is the expected behaviour.

param: bool $multiple if send multiple statements (adds one valid statement)
param: bool $validactor if the actor used is valid
param: bool $validverb if the verb used is valid
param: array $expected expected results

test_statements_group(bool $multiple, bool $validactor, bool $validverb, array $expected)   X-Ref
Testing group statements.

This function test several scenarios using different combinations
of statement rejection motives. Some motives produces a full batch
rejection (exception) and other can leed to indivual rejection on
each statement. For example,try to post a statement without $USER
in it produces a full batch rejection, while using an invalid
verb on one statement just reject that specific statement
That is the expected behaviour.

param: bool $multiple if send multiple statements (adds one valid statement)
param: bool $validactor if the actor used is valid
param: bool $validverb if the verb used is valid
param: array $expected expected results

statement_provider()   X-Ref
Data provider for the test_components tests.

return: array

test_group_disabled(bool $usegroup1, bool $usegroup2, array $expected)   X-Ref
Test posting group statements to a handler without group actor support.

Try to use group statement in components that not support this feature
causes a full statements batch rejection.

param: bool $usegroup1 if the 1st statement must be groupal
param: bool $usegroup2 if the 2nd statement must be groupal
param: array $expected expected results

group_statement_provider()   X-Ref
Data provider for the test_components tests.

return: array

test_full_batch_rejected()   X-Ref
Test posting a statements batch not accepted by handler.

If all statements from a batch are rejectes by the plugin the full
batch is considered rejected and an exception is returned.
