manifest-ldf-tests

A repository containing test-manifests that can be used to do integration testing. Based on the ontology-query-testing and used in the rdf-test-suite-ldf.js.

Content

This repository consists of 4 test manifests that can be used to test the 4 query-engines of comunica.

manifest name	manifest URI	tested sources
SPARQL	sparql-manifest.ttl	TPF, FILE, SPARQL
SPARQL-FILE	file-manifest.ttl	FILE
SPARQL-HDT	hdt-manifest.ttl	HDT
SPARQL-RDFJS	rdfjs-manifest.ttl	RDFJS

How to add new queries

In most cases, you'll want to add queries to the sparql/sparql-manifest.ttl.

To do this, you'll have to do the following:

1. Globally install ldf-recorder. If you made changes to Comunica that were not released yet, you may have to clone https://github.com/comunica/ldf-recorder, link your local @comunica/query-sparql, and use that instance of ldf-recorder for recording.
2. Add your new query entry to sparql/manifest-raw.txt. The expected format is test label and sources. If you want to record over plain files, then you may have to temporarily host the file on localhost (e.g. using http-server), and define it as such in sparql/manifest-raw.txt. After generating, make sure to add both the original file and the recorded file to git, and update sparql/manifest-raw.txt to refer to the original file via the URL as it will exist on GitHub (see how this is done in the other tests).
3. Run ./generate.sh to generate the expected outputs of all tests in sparql/manifest-raw.txt. You could temporarily omit elements from sparql/manifest-raw.txt to only generate those test outputs that have changed.
4. Add your new query entry to sparql/sparql-manifest.ttl.
5. After testing and pushing, this can be tested in Comunica by running yarn run integration inside engines/query-sparql.

queries

A lot of the queries are inspired by the pre-built queries on query.linkeddatafragments.org.
