So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

I tested several ideas in the most popular Python editors: PyCharm, VS Code, Jedi based editors.

    private val functionalTestBucketProvider = StatisticBasedFunctionalTestBucketProvider(model, testBucketsJson)
    override fun createFunctionalTestsFor(stage: Stage, testCoverage: TestCoverage): List<FunctionalTest> {
        return when {
            testCoverage.testType == TestType.quickFeedbackCrossVersion -> quickCrossVersionTestBucketProvider.createFunctionalTestsFor(stage, testCoverage)

    MutableNetwork<Integer, String> g1 = builder.build();
    MutableNetwork<Integer, String> g2 = builder.build();

    // for ug1, add e12 first, then e12_a
    g1.addEdge(N1, N2, E12);
    g1.addEdge(N1, N2, E12_A);

    // for ug2, add e12_a first, then e12
    g2.addEdge(N1, N2, E12_A);
    g2.addEdge(N1, N2, E12);

    assertThat(g1).isEqualTo(g2);
  }

  @Test

    MutableNetwork<Integer, String> g1 = builder.build();
    MutableNetwork<Integer, String> g2 = builder.build();

    // for ug1, add e12 first, then e12_a
    g1.addEdge(N1, N2, E12);
    g1.addEdge(N1, N2, E12_A);

    // for ug2, add e12_a first, then e12
    g2.addEdge(N1, N2, E12_A);
    g2.addEdge(N1, N2, E12);

    assertThat(g1).isEqualTo(g2);
  }
