Playground standard covoiturage

A tool to test an API against the standard-covoiturage specification:

• A test server with fake in-memory data to play with the standard API.
• A client that runs a test against a server request.

The tool is currently being developped. More about the aimed functional scope here (fr).

Install

You can find and download the executable for various platforms here, or clone the repo and enter go build -o pscovoit in the root folder.

Run the fake server

The serve subcommand runs the server on http://localhost:1323 (port not customizable yet):

./pscovoit serve

The served data can be inspected here, or custom data can be used with the --data flag pointing to a valid json data file (check-out type MockDBDataInterface for more details on data structure).

Test a request

The test subcommand runs tests on a given request.

There are several ways to specify the request, the three examples below are equivalent:

• through an url (̀method flag is set to GET by default and could be omitted here)

./pscovoit test \
--url "http://localhost:1323/driver_journeys?arrivalLat=48.8450234&arrivalLng=2.3997529&departureDate=1665579951&departureLat=47.461737&departureLng=1.061393" \
--method=GET

• through an url with (some or all) query parameters as flags

./pscovoit test --url "http://localhost:1323/driver_journeys" \
  -q arrivalLat=48.8450234 \
  -q arrivalLng=2.3997529 \
  -q departureDate=1665579951 \
  -q departureLat=47.461737 \
  -q departureLng=1.061393

• through subcommands

./pscovoit test get driverJourneys \
  --server "http://localhost:1323" \
  --arrivalLat=48.8450234 \
  --arrivalLng=2.3997529 \
  --departureDate=1665579951 \
  --departureLat=47.461737 \
  --departureLng=1.061393

A request body can be read from standard input, e.g.:

• Read from file

pscovoit test post bookings <file_with_body.txt

• Passed as string

pscovoit test post bookings <<< "{body}"

By default, only the failed tests are reported. Use the --verbose flag to see all tests and additional information.

Autocompletion

The last method may greatly benefit from autocompletion.

This is possible if the binary is in $PATH, see for more information:

./pscovoit completion --help

Use in CI

The tool returns exit code 1 in case of an assertion failure. See a simple example of use in github CI here (github workflow) and here (test commands scripts).

Tests and assertions

Test Flags

• --expectResponseCode: additional check that the HTTP response code is as expected
• --expectNonEmpty (array responses): additionnal check that this array is not empty.
• --expectBookingStatus (GET /bookings): additional check that the booking has the expected booking status.

Example tests

For an example of a thorough test suite for an API, look at this example, that works together with this data.

GET /driver_journey, GET /passenger_journey, GET /driver_regular_trips, GET/passenger_regular_trips

The following assertions are run on these two endpoints :

• assert format
• assert response status code 200 (optional)
• assert header Content-Type:application/json
• assert query parameter "departureRadius"
• assert query parameter "arrivalRadius"
• assert query parameter "timeDelta"
• assert query parameter "count"
• assert unique ids
• assert response property "operator"

POST /bookings, POST /booking_events, PATCH /bookings, POST /messages

• assert format
• assert response status code (optional)

GET /bookings

• assert format
• assert response status code (optional)
• assert booking status (optional)

Assertions reference

In alphabetic order:

Assertion code	description
assert API call success	Checks that the response data has been succesfully collected
assert format	Checks that the format of the response complies to the standard's openAPI specification. Especially, the observed status code needs to be documented.
assert header X:Y	Checks that the response has header X with value Y.
assert query parameter X	Checks that the response complies to the expectations of the queryparameter X.
assert response not empty	Checks that the response is not an empty array.
assert response property X	Checks that the response property X meets the expectations given by the standard.
assert response status code X	Checks that the status code X is returned.
assert unique ids	Checks that the response objects have no duplicated "id" property.

Release

Releases are made with goreleaser.
