## Running and debugging the application
2021-01-26 15:05:33 +00:00
### Running the application from the command line.
To run from the command line, use `mvn` and open http://localhost:8080 in your browser.
### Running and debugging the application in Intellij IDEA
- Locate the Application.java class in the Project view. It is in the src folder, under the main package's root.
- Right click on the Application class
- Select "Debug 'Application.main()'" from the list
2021-03-08 09:53:59 +00:00
After the application has started, you can view it at http://localhost:8080/ in your browser.

You can now also attach break points in code for debugging purposes, by clicking next to a line number in any source file.
### Running and debugging the application in Eclipse
- Locate the Application.java class in the Package explorer. It is in `src/main/java`, under the main package.
- Right click on the file and select `Debug As` --> `Java Application`.
Do not worry if the debugger breaks at a `SilentExitException`. This is a Spring Boot feature and happens on every startup.

## Fuzzing with [JQF](https://github.com/rohanpadhye/JQF)
### [Zest](https://github.com/rohanpadhye/JQF/wiki/Fuzzing-with-Zest)
Run:
```
mvn test-compile jqf:fuzz -Dclass=edu.kit.typicalc.model.parser.LambdaParserFuzzTest -Dmethod=testInference
```
This will use the `LambdaTermGenerator` to create random lambda terms that are then passed to the `ModelImpl`.
### [AFL](https://lcamtuf.coredump.cx/afl/)
First install the necessary JQF tools: https://github.com/rohanpadhye/jqf/wiki/Fuzzing-with-AFL
2021-01-26 15:05:33 +00:00
2021-03-08 09:53:59 +00:00
Remove the `@Ignore` annotation in `LambdaParserFuzzTest` and run:
```
mvn test-compile
jqf-afl-fuzz -c target/test-classes:target/classes -i src/test/resources/terms/ edu.kit.typicalc.model.parser.LambdaParserFuzzTest testLambdaParserAFL
```

2021-03-08 09:53:59 +00:00
Generated inputs are stored in `fuzz-results/queue/`.
More samples can be added to `src/test/resources/terms/` to speed up the process.
