## First Steps { #first-steps }

Let's see a very simple example. It will be so simple that it is not very useful, for now.

But this way we can focus on how the **Dependency Injection** system works.

### Create a dependency, or "dependable" { #create-a-dependency-or-dependable }

Let's first focus on the dependency.

        // Given
        when(mockTreeHandle.isSMB2()).thenReturn(true);
        when(mockTreeHandle.getSendBufferSize()).thenReturn(65536);
        when(mockFileHandle.isValid()).thenReturn(false, true); // First false to trigger ensureOpen, then true
        when(mockFileHandle.getFileId()).thenReturn(new byte[16]);
        when(mockFileHandle.acquire()).thenReturn(mockFileHandle);

        // Mock for ensureOpen to reopen file

  }

  /*
   * TODO(b/242884182): Figure out why this helps produce the same class file when we compile most
   * of common.collect a second time with the results of the first compilation on the classpath. Or
   * just back this out once we stop doing that (which we'll do after our internal GWT setup
   * changes).

  @Override
  public ImmutableMap<Object, Collection<Object>> asMap() {

        RescorerBuilder<?> result = queryRescorer.evaluate(params);
        assertNotNull(result);
    }

    public void test_evaluate_multipleImplementations() {
        // Test with first implementation
        QueryRescorer rescorer1 = new QueryRescorer() {
            @Override
            public RescorerBuilder<?> evaluate(Map<String, Object> params) {
                return createMockRescorerBuilder();

        // Each setInstance should create a new LogStream
        assertNotNull(instance1);
        assertNotNull(instance2);
        // The second setInstance replaces the first, so they should not be the same
        assertNotSame(instance1, instance2);
        // Getting instance again should return the same as instance2
        assertSame(instance2, LogStream.getInstance());
    }
