Sprint Planning Doc for F24:

• https://docs.google.com/document/d/1XsaIPgepB4uA3owsH8eszXbW2mHFTuW5_bT49K8PcuU/edit?tab=t.0

Versions

• Java: 21
• node: 20.17.0 See docs/versions.md for more information on upgrading versions.

Setup before running application

Before running the application for the first time, you need to do the steps documented in docs/oauth.md.

Otherwise, when you try to login for the first time, you will likely see an error such as:

Getting Started on localhost

• Open two separate terminal windows
• In the first window, start up the backend with:

  mvn spring-boot:run

• In the second window:

  cd frontend
  npm install  # only on first run or when dependencies change
  npm start

Then, the app should be available on http://localhost:8080

If it doesn't work at first, e.g. you have a blank page on http://localhost:8080, give it a minute and a few page refreshes. Sometimes it takes a moment for everything to settle in.

If you see the following on localhost, make sure that you also have the frontend code running in a separate window.

Failed to connect to the frontend server... On Dokku, be sure that PRODUCTION is defined.  On localhost, open a second terminal window, cd into frontend and type: npm install; npm start";

Getting Started on Dokku

See: /docs/dokku.md

Accessing swagger

To access the swagger API endpoints, use:

• http://localhost:8080/swagger-ui/index.html

Or add /swagger-ui/index.html to the URL of your dokku deployment.

To run React Storybook

• cd into frontend
• use: npm run storybook
• This should put the storybook on http://localhost:6006
• Additional stories are added under frontend/src/stories

For documentation on React Storybook, see:

• https://ucsb-cs156.github.io/topics/storybook/
• https://ucsb-cs156.github.io/topics/chromatic/
• https://storybook.js.org/

SQL Database access

On localhost:

• The SQL database is an H2 database and the data is stored in a file under target
• Each time you do mvn clean the database is completely rebuilt from scratch
• You can access the database console via a special route, http://localhost:8080/h2-console
• For more info, see docs/h2-database.md

On Dokku, follow instructions for Dokku databases:

• https://ucsb-cs156.github.io/topics/dokku/postgres_database.html

Testing

Unit Tests

• To run all unit tests, use: mvn test
• To run only the tests from FooTests.java use: mvn test -Dtest=FooTests

Unit tests are any methods labelled with the @Test annotation that are under the /src/test/java hierarchy, and have file names that end in Test or Tests

Integration Tests

To run only the integration tests, use:

INTEGRATION=true mvn test-compile failsafe:integration-test

To run only the integration tests and see the tests run as you run them, use:

INTEGRATION=true HEADLESS=false mvn test-compile failsafe:integration-test

To run a particular integration test (e.g. only HomePageWebIT.java) use -Dit.test=ClassName, for example:

INTEGRATION=true mvn test-compile failsafe:integration-test -Dit.test=HomePageWebIT

or to see it run live:

INTEGRATION=true HEADLESS=false mvn test-compile failsafe:integration-test -Dit.test=HomePageWebIT

Integration tests are any methods labelled with @Test annotation, that are under the /src/test/java hierarchy, and have names starting with IT (specifically capital I, capital T).

By convention, we are putting Integration tests (the ones that run with Playwright) under the package src/test/java/edu/ucsb/cs156/example/web.

Unless you want a particular integration test to also be run when you type mvn test, do not use the suffixes Test or Tests for the filename.

Note that while mvn test is typically sufficient to run tests, we have found that if you haven't compiled the test code yet, running mvn failsafe:integration-test may not actually run any of the tests.

Partial pitest runs

This repo has support for partial pitest runs

For example, to run pitest on just one class, use:

mvn pitest:mutationCoverage -DtargetClasses=edu.ucsb.cs156.rec.controllers.RestaurantsController

To run pitest on just one package, use:

mvn pitest:mutationCoverage -DtargetClasses=edu.ucsb.cs156.rec.controllers.\*

To run full mutation test coverage, as usual, use:

mvn pitest:mutationCoverage
