ExtremeRegression shows regression with >15% pass rate change.

ExtremeTriagedRegression shows an ExtremeRegression that clears when Triaged incidents are factored in.

MissingBasis indicates basis data missing.

MissingBasisAndSample indicates basis and sample data missing.

MissingSample indicates sample data missing.

NotSignificant indicates no significant difference.

SignificantImprovement indicates improved sample rate.

SignificantRegression shows significant regression.

SignificantTriagedRegression shows a SignificantRegression that clears when Triaged incidents are factored in.

JobVariant defines a variant and the possible values.

JobVariants contains all variants supported in the system.

PullRequestOptions specifies a specific pull request to use as the basis or (more often) sample for the report.

ReportTestStats is an overview struct for a particular regressed test's stats.

RequestOptions is a struct packaging all the options for a CR request.

RequestRelativeReleaseOptions is an unfortunate necessity for views where we do not have a fixed time, rather a relative time to now/ga.

TestIdentification TODO: we need to get Network/Upgrade/Arch/Platform/FlatVariants off this struct as the actual variants will be dynamic.

TestRegression is used for rows in the test_regressions table and is used to track when we detect test regressions opening and closing.

Variant is currently only used with TriagedIncidents.

View is a server side construct representing a predefined view over the component readiness data.

Comparison is the type of comparison done for a test that has been marked red.
