End to end tests

E2e tests largely follow the same syntax as integration tests. Whereas integration tests are intended to mock and stress the back-end, server-side code, e2e tests the interface between front-end and back-end, as well as visual regressions with both assertions and visual comparisons. They can be run with make commands for the appropriate backends, namely:

make test-sqlite
make test-pgsql
make test-mysql
make test-mysql8
make test-mssql

Make sure to perform a clean front-end build before running tests:

make clean frontend

Install playwright system dependencies

npx playwright install-deps

Run all tests via local drone

drone exec --local --build-event "pull_request"

Run sqlite e2e tests

Start tests

make test-e2e-sqlite

Run MySQL e2e tests

Setup a MySQL database inside docker

docker run -e "MYSQL_DATABASE=test" -e "MYSQL_ALLOW_EMPTY_PASSWORD=yes" -p 3306:3306 --rm --name mysql mysql:latest #(just ctrl-c to stop db and clean the container)
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --rm --name elasticsearch elasticsearch:7.6.0 #(in a second terminal, just ctrl-c to stop db and clean the container)

Start tests based on the database container

TEST_MYSQL_HOST=localhost:3306 TEST_MYSQL_DBNAME=test TEST_MYSQL_USERNAME=root TEST_MYSQL_PASSWORD='' make test-e2e-mysql

Run pgsql e2e tests

Setup a pgsql database inside docker

docker run -e "POSTGRES_DB=test" -p 5432:5432 --rm --name pgsql postgres:latest #(just ctrl-c to stop db and clean the container)

Start tests based on the database container

TEST_PGSQL_HOST=localhost:5432 TEST_PGSQL_DBNAME=test TEST_PGSQL_USERNAME=postgres TEST_PGSQL_PASSWORD=postgres make test-e2e-pgsql

Run mssql e2e tests

Setup a mssql database inside docker

docker run -e "ACCEPT_EULA=Y" -e "MSSQL_PID=Standard" -e "SA_PASSWORD=MwantsaSecurePassword1" -p 1433:1433 --rm --name mssql microsoft/mssql-server-linux:latest #(just ctrl-c to stop db and clean the container)

Start tests based on the database container

TEST_MSSQL_HOST=localhost:1433 TEST_MSSQL_DBNAME=gitea_test TEST_MSSQL_USERNAME=sa TEST_MSSQL_PASSWORD=MwantsaSecurePassword1 make test-e2e-mssql

Running individual tests

Example command to run example.test.e2e.js test file:

Note: unlike integration tests, this filtering is at the file level, not function

For SQLite:

make test-e2e-sqlite#example

For other databases(replace mssql to mysql, mysql8 or pgsql):

TEST_MSSQL_HOST=localhost:1433 TEST_MSSQL_DBNAME=test TEST_MSSQL_USERNAME=sa TEST_MSSQL_PASSWORD=MwantsaSecurePassword1 make test-e2e-mssql#example

Visual testing

Although the main goal of e2e is assertion testing, we have added a framework for visual regress testing. If you are working on front-end features, please use the following:

• Check out main, make clean frontend, and run e2e tests with VISUAL_TEST=1 to generate outputs. This will initially fail, as no screenshots exist. You can run the e2e tests again to assert it passes.
• Check out your branch, make clean frontend, and run e2e tests with VISUAL_TEST=1. You should be able to assert you front-end changes don't break any other tests unintentionally.

VISUAL_TEST=1 will create screenshots in tests/e2e/test-snapshots. The test will fail the first time this is enabled (until we get visual test image persistence figured out), because it will be testing against an empty screenshot folder.

ACCEPT_VISUAL=1 will overwrite the snapshot images with new images.
