# Reservations API
2+
3+
Simple API built with SpringBoot and MongoDB database.
4+
5+
## Documentation
6+
7+
Documentation can be found [here](https://cg-reservations-api.herokuapp.com/documentation)
8+
9+
## How to run
10+
11+
### Application
12+
13+
1. Clone the repository by executing commands:
14+
15+
```
16+
cd <yourRepoDirectory>
17+
git clone https://github.com/cyrilgavala/reservations-api.git .
18+
```
19+
20+
2. Open the project with your preferable IDE.
21+
If you use IntelliJ IDEA, it will offer you a **SpringBoot** runner configuration.
22+
3. Update the runner by adding environment variable ```DATABASE_URL``` containing
23+
URL to your MongoDB database and ```JWT_SECRET``` with 512-bit secret.
24+
4. Run the runner configuration.
25+
26+
### Tests
27+
28+
1. To run tests you need to pass step 2. from previous instructions and run command:
29+
30+
```./gradlew test```
31+
32+
It will also execute ```jacocoTestReport``` gradle task, which will generate
33+
test report on path ```reservation-api/build/reports/jacoco/test/html/index.html```.
34+
2. To run whether you pass 95% test coverage check, simply run command:
35+
36+
```./gradlew jacocoTestCoverageVerification```
