We currently have two different entry points for configuration. One, the Services.Configuration, is used for specifying where to find custom value formatters and which test framework to use, and can be configured through app.config (provided the .NET platform supports that). The other, AssertionOptions, is used to change formatting settings and alter the equivalency plan.

Current idea:

static class AssertionOptions

• Initialized through EnsureInitialized() and can be reset using Reset()
• Properties
  • EquivalencyPlan
  • Formatting (FormattingOptions)
  • Equivalency (EquivalencyOptions)
  • ValueFormatters
    • DetectionMode
    • AssemblyToScan
  • TestFrameworkName

static class AssertionRuntime

• Executes custom initializers
• Properties
  * ThrowException
  * TestFramework (ITestFramework)
