Automated testing

Cypress.io is used for testing this plugin. The following steps show how to run the tests locally.

1. Install JBrowse but don’t install chromosome files.
2. Download Chr 1 fasta from http://ftp.ensembl.org/pub/release-94/fasta/homo_sapiens/dna/Homo_sapiens.GRCh38.dna.chromosome.1.fa.gz. There should be the fasta index file in cypress/data/Homo_sapiens.GRCh38.dna.chromosome.1.fa.fai. Put these files into jbrowse/data/.
3. Install Cypress.io with npm install.
4. Place cypress/data/tracks.conf into your jbrowse/data/ directory. Make sure no other tracks are present.
5. Run npx cypress open or npx cypress run or npm run e2e

Note while some tests have mocked endpoints, not all endpoints are mocked. This could lead to breakage of tests in the future.
