Test naming

Pattern: MethodName_StateUnderTest_ExpectedBehavior

Required abstract methods

Compile errors if missing. Additional tests are developer discretion.

Series (StaticSeriesTestBase):

• DefaultParameters_ReturnsExpectedResults()
• BadQuotes_DoesNotFail()
• NoQuotes_ReturnsEmpty()

Buffer (BufferListTestBase):

• PruneList_OverMaxListSize_AutoAdjustsListAndBuffers()
• Clear_WithState_ResetsState()
• Plus interface methods from ITestQuoteBufferList or ITestChainBufferList (see patterns reference)

Stream (StreamHubTestBase):

• ToStringOverride_ReturnsExpectedName()
• Plus interface methods from ITestQuoteObserver, ITestChainObserver, and/or ITestChainProvider (see patterns reference)

Test data

Data.GetDefault() — 502 quotes. Use consistently across all tests.
