 A makefile provides some useful commands:
  - `make build` to compile the base ff algorithm. This creates an ftest.native executable
- - `make test` to run the `ftest` program with some arguments and generate svg files for each tests. You must first uncomment the tests in the `ftest` file. This uses graphs in the `graphs` folder and outputs in the `test` folder.
+ - `make test` to run the `ftest` program without arguments (executes tests) and generate svg files for each tests. This uses the `graph1` in the `graphs` folder and outputs in the `test` folder.
  - `make demo` to run the `ftest` program with some arguments and generate the final svg file. This uses graphs in the `graphs` folder and outputs in the `run` folder.
  - `make build_circulation` to compile the circulation-demand problem resolution. This creates a circulationtest.native executable
  - `make demo_circulation` to run the `circulationtest` program with some arguments and generate the final svg file. This uses graphs in the `circulation_input_graphs` folder and outputs in the `run` folder.
