ont-app.igraph.test-support — ont-app/igraph 0.2.0

These are tests that should be applicable to implemenations of the IGraph protocols. Most examples are drawn from the README. After running tests, query-for-failures should be empty.

• report is an atom containing the report graph
• test-name is a KWI naming a test
• comment is a string describing the test
• observed is some value derived when running the test
• expected is the expected value of running the test. NOTE: if observed=expected, test-name will be of type ::Passed, else ::Failed.

do-report! clj/s

(do-report! report desc)

Side-effect: Modifies report in include desc. Returns @report Where

• report is an atom containing the report graph
• desc is a normal-form description to be added to report

eg-data clj/s

Initial data for the eg graph in the README

eg-with-types-data clj/s

Data to populate a test graph with the eg-with-types example graph in README

other-eg-data clj/s

Contents of the other-eg graph in the README

query-for-failures clj/s

(query-for-failures report)

Returns #{failure-binding,...} for report Where

• failure-binding := m s.t. (keys m) :~ #{:?test :?comment :?observed :?expected}
• report is a graph put out by one or more tests in test-support
• :?test names a test
• :?comment is a string
• :?observed is the value acquired in the test
• :?expected is the expected value of :?observed
• NOTE: a passing report should return an empty set.

report-invalid-test-graph clj/s

(report-invalid-test-graph report
                           test-graph
                           &
                           {:keys [test-fn-var protocol content-var
                                   schema-graph]})

Returns report' if test-graph is not valid, otherwise nil. Where

• report is a report graph
• test-graph is a graph provided for a test
• test-fn-var is a #'var naming the operative test protocolis the expected protocol fortest-graph`
• content-var is the var naming the test content, eg #'eg-data
• schema-graph (optional) is a graph initialized with any required schema, but otherwise free of content. Default is nil. NOTE: typical pattern is (or (report-invalid-test-graph ...) (<do-the-actual-tests>))

run-standard-implementation-tests clj/s

(run-standard-implementation-tests report)

One-liner to test a fully-featured implemenation of all the IGraph protocols.

sans-schema clj/s

(sans-schema g schema-graph)

Returns a native-normal graph with the contents of g minus schema-graph Where

• g is the test graph implementing IGraph and containing test content
• schema is a properly configured graph devoid of test content, or nil NOTE: Some graph implementations will require that you declare a schema up-front, for example Datascript or Datomic. We'll need to extract this before we confirm that we're starting with valid test content.

subClassOf* clj/s

A traversal function. Transitive closure of subClassOf

test-cardinality-1 clj/s

(test-cardinality-1 report)

Returns report' using a graph containing data from the README Where

• report is a report graph
• cardinality-1-graph contains cardinality-1-graph-data plus maybe the contents of schema-graph
• schema-graph is nil, or contains initialization data required by your igraph implementation. NOTE: these tests all relate to cardinality-1 behavior as documented in the README.

test-readme-eg-access clj/s

(test-readme-eg-access report)

Returns report' for report, given eg-graph, possibly informed by readme-schema-graph Where

• report is a native-normal IGraph recording tests and their outcomes
• eg-graph is a graph in the target IGraph implementation containing readme-example-content, created per the configuration of report
• readme-schema-graph (optional) is a target IGraph implementation initialized with whatever schema configuration is required by the target implementation. (Datascript for example). Default is nil. NOTE: these tests are for the access functions defined for IGraph.

test-readme-eg-mutation clj/s multimethod

Returns report', modified per tests on mutability, dispatched on the mutability attribute of the graph under examination.

test-readme-eg-mutation-dispatch clj/s

(test-readme-eg-mutation-dispatch report)

Returns the mutability of a graph made according to the report's ::makeGraphFn

test-readme-eg-mutation-fn clj/s

(test-readme-eg-mutation-fn context report)

Returns report', given eg-graph and maybe schema-graph if needed, informed by context Where

• report is a graph containing test results
• eg-graph contains eg-data, drawn from examples in the README.
• schema-graph is nil, or contains initialization data required by your igraph implementation.
• context := m s.t. (keys m) :~ #{:test-fn-var :protocol :add-fn :subtract-fn :assert-unique-fn}
• test-fn-var is a var naming the test function for the :inTest attr in the report
• protocol is the mutability protocol implemented in eg-graph
• add-fn is a function appropriate to protocol for adding to eg-graph
• subtract-fn is a function appropriate to protocol for removing from eg-graph.
• assert-unique-fn is a function appropriate to protocol for asserting a triple whose object is a singleton (should clobber any previous object).

test-readme-eg-set-operations clj/s

(test-readme-eg-set-operations report)

Returns report', given eg-graph based on README examples Where

• report is a graph containing test results

• report is a native-normal graph
• eg-with-types-graph is an instance of the target graph initialized with eg-data + eg-with-types-data, created per the configuration of report. NOTE: these tests all have to do with traversal.
