Feature/22 test handling incoming events (#30)

* Checkpoint before the weekend * Update location for SetupPostgresDB * Include first functioning tests for processing head * Fix gitignore * Test CaptureHead | Add Metrics | Handle Test Race Conditions This Commit allows us to: * Test the `CaptureHead` function. * Test parsing a single Head message. * Test a Reorg condition. * Add Metrics. This is primarily used for testing but can have future use cases. * Rearrange the test due to race conditions introduced by reusing a variable. `BeforeEach` can't be used to update `BC`. * Update and finalize testing at this stage * Update code and CI/CD * Fix lint errors * Update CICD and fail when file not found. * Update test to have failed as expected.

+## Running the Application
+
+To run the application, do as follows:
+
+1. Setup the prerequisite applications.
+   a. Run a beacon client (such as lighthouse).
+   b. Run a postgres DB.
+   c. You can utilize the `stack-orchestrator` [repository](https://github.com/vulcanize/stack-orchestrato).

+## Running Tests
+
+To run tests, you will need to clone another repository which contains all the ssz files.
+
+1. `git clone git@github.com:vulcanize/ssz-data.git pkg/beaconclient/ssz-data`
+2. To run unit tests, make sure you have a DB running: `make unit-test-local`
+3. To run integration tests, make sure you have a lighthouse client and a DB running: `make integration-test-local-no-race` .

 # Development Patterns

 This section will cover some generic development patterns utilizes.
@ -58,9 +86,18 @@ This project utilizes `ginkgo` for testing. A few notes on testing:
 - All test packages are named `{base_package}_test`. This ensures we only test the public methods.
 - If there is a need to test a private method, please include why in the testing file.
 - Unit tests must contain the `Label("unit")`.
- Unit tests should not rely on any running service. If a running service is needed. Utilize an integration test.
+- Unit tests should not rely on any running service (except for a postgres DB). If a running service is needed. Utilize an integration test.
 - Integration tests must contain the `Label("integration")`.

+#### Understanding Testing Components
+
+A few notes about the testing components.
+
+- The `TestEvents` map contains several events for testers to leverage when testing.
+- Any object ending in `-dummy` is not a real object. You will also notice it has a present field called `MimicConfig`. This object will use an existing SSZ object, and update the parameters from the `Head` and `MimicConfig`.
+  - This is done because creating an empty or minimal `SignedBeaconBlock` and `BeaconState` is fairly challenging.
+  - By slightly modifying an existing object, we can test re-org, malformed objects, and other negative conditions.
