‘jsondata.Selftest’ - Module

Test of basic features for the user by ‘–selftest’.

This module is used by ‘jsondc’ when the opverify_data_schemaardoced basic functional checks by calling ‘runselftest’.

The display of actions and results could be activated and raised by multiple repetition of the ‘-v’ option.

The following data and schema are applied:

0. jsondata/data.json + jsondata/schema.jsd
1. jsondata/datacheck.json + jsondata/datacheck.jsd

The performed process flow is:

0. load
1. validate
2. verify

By default either ‘True’ is returned, or in case of a failed test and/or error condition an exception is raised.

Basic

• runselftest

jsondata.Selftest.runselftest(appname='selftest', **kargs)

Performs the selftest returns True or False. Executes some the basic runtime test cases for user verification.

Args:

appname: Name of the application. Changing this may break the

selftest. default:=selftest

**kargs:

debug: Displays extended state data for developers.

Requires __debug__==True.

verbose: Extends the amount of the display of

processing data.

_verbose=#levels: Extends the amount of the display

of processing data by given number of levels at once.

Returns:

Selftest object.

Raises:

bypassed subsystems

• printverbose

jsondata.Selftest.printverbose(lvl, args)

Load Tests

• load_data

jsondata.Selftest.load_data(appname)

Loads and verifies the self test ‘data.json’.

Therefore the result of the creation of JSONDataSerializer is compared to the load by json.load().

• load_appname

jsondata.Selftest.load_appname(appname)

Loads and verifies the self test ‘selftest.json’.

Therefore the result of the creation of JSONDataSerializer is compared to the load by json.load().

Validation Tests

• verify_data_schema

jsondata.Selftest.verify_data_schema(appname)

Loads and validates the self test ‘data.json’ and ‘schema.jsd’.

Therefore the result of the creation of JSONDataSerializer is performed with draft3 validation by jsonschema.validate().

• verify_appname_schema

jsondata.Selftest.verify_appname_schema(appname)

Loads and validates the self test ‘selftest.json’ and ‘selftest.jsd’.

Therefore the result of the creation of JSONDataSerializer is performed with draft3 validation by jsonschema.validate().

JSONPointer tests

• jsonpointer_data_schema

jsondata.Selftest.jsonpointer_data_schema(appname)

Loads and verifies by using JSONPointer access ‘data.json’.

• jsonpointer_selftest_data

jsondata.Selftest.jsonpointer_selftest_data(appname)

Loads and verifies by using JSONPointer access ‘selftest.json’.

• jsonpointer_selftest_data_schema

jsondata.Selftest.jsonpointer_selftest_data_schema(appname)

Loads and verifies by using JSONPointer access ‘selftest.json’.
