Try-Catch Boundary testing

Code is easy, state is hard

Try-Catch is a test utility to automate labourious API call + database checking tasks when doing manual testing. The utility follows three simple steps to accomodate full end-to-end test of your API exposing web application:

1. Initialize Database with wanted values
2. Make an API call and check that the response from API matches expected
3. Run a database query and assert that expected rows are returned.

The application has two modes: WEB and CLI

• On web mode you can navigate to localhost:7357 with your browser and use the GUI to build, test and save your test cases.
• On CLI mode the application reads scenario JSON files from your scenario-folder that you have set in your properties.yaml. These scenarios are run automatically and result are printed out to the console.

To setup

1. Clone the repository.
2. Set up you database connection strings in db.yml file that you can find from the conf folder.
3. Run the application with ./gradlew run.

To deploy and distribute

1. Clone the repository
2. Create an executable jar by running ./gradlew shadowJar from the command line.
3. Move you generated jar file from build/libs folder to the installation location.
4. Move the conf folder to the installation location.
5. Setup your database connection strings and scenario location settings in db.yml and properties.yml
6. Run the application:

• In web mode: java -jar trycatch-all.jar
• In CLI mode: java -jar trycatch-all.jar cli

To develop further

The web application is built using Ratpack on top of Kotlin on the backend and React on the frontend. API calls are made using okHttp3 and responses are wrapped in RxJava/RxKotlin observables. Database connection is handled by JDBC and HikariCP, sessions are handled by KotlinQuery. Database responses are again wrapped in RxJava/RxKotlin observables. React components are loosely typed with the help of Flow. Dependency injection framework in use is Guice. Build processes are handled by Gradle in the backend and Webpack on the frontend. To startup the Ratpack server on dev mode you have two options (from the root folder of the project):

• Standard: gradle run
• Continuous: gradle run -t

If you don't have gradle installed:

• Standard: ./gradlew run
• Continuous: ./gradlew run -t

To start frontend development server you have two options(from the folder src/ratpack/static):

• Standard: npm run build
• Continuous with auto reload: npm start

Note that you need to have run npm install before starting developing on the frontend.
