▼NData
CAndroidAppInfo	Android app information.
CAndroidInstrumentationTest	A test of an Android application that can control an Android component independently of its normal lifecycle
CAndroidRoboTest	A test of an android application that explores the application on a virtual or physical Android device, finding culprits and crashes as it goes.
CAndroidTest	An Android mobile test specification.
CAny	`Any` contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message
CAppStartTime
CBasicPerfSampleSeries	Encapsulates the metadata for basic sample series represented by a line chart
CBatchCreatePerfSamplesRequest	The request must provide up to a maximum of 5000 samples to be created; a larger sample size will cause an INVALID_ARGUMENT error
CBatchCreatePerfSamplesResponse
CCPUInfo
CDuration	A Duration represents a signed, fixed-length span of time represented as a count of seconds and fractions of seconds at nanosecond resolution. It is independent of any calendar and concepts like "day" or "month". It is related to Timestamp in that the difference between two Timestamp values is a Duration and it can be added or subtracted from a Timestamp. Range is approximately +-10,000 years
CEnvironment	An Environment represents the set of test runs (Steps) from the parent Execution that are configured with the same set of dimensions (Model, Version, Locale, and Orientation). Multiple such runs occur particularly because of features like sharding (splitting up a test suite to run in parallel across devices) and reruns (running a test multiple times to check for different outcomes).
CEnvironmentDimensionValueEntry
CExecution	An Execution represents a collection of Steps. For instance, it could represent: - a mobile test executed across a range of device configurations - a jenkins job with a build step followed by a test step
CFailureDetail	Details for an outcome with a FAILURE outcome summary.
CFileReference	A reference to a file.
CGraphicsStats	Graphics statistics for the App. The information is collected from 'adb shell dumpsys graphicsstats'. For more info see: https://developer.android.com/training/testing/performance.html Statistics will only be present for API 23+.
CGraphicsStatsBucket
CHistory	A History represents a sorted list of Executions ordered by the start_timestamp_millis field (descending). It can be used to group all the Executions of a continuous build
CImage	An image, with a link to the main image and a thumbnail.
CInconclusiveDetail	Details for an outcome with an INCONCLUSIVE outcome summary.
CIndividualOutcome	Step Id and outcome of each individual step that was run as a group with other steps with the same configuration.
CListEnvironmentsResponse	Response message for EnvironmentService.ListEnvironments.
CListExecutionsResponse
CListHistoriesResponse	Response message for HistoryService.List
CListPerfSampleSeriesResponse
CListPerfSamplesResponse
CListScreenshotClustersResponse
CListStepsResponse	Response message for StepService.List.
CListStepThumbnailsResponse	A response containing the thumbnails in a step.
CListTestCasesResponse	Response message for StepService.ListTestCases.
CMemoryInfo
CMergedResult	Merged test result for environment
CMultiStep	Details when multiple steps are run with the same configuration as a group.
COutcome	Interprets a result so that humans and machines can act on it.
CPerfEnvironment	Encapsulates performance environment info
CPerfMetricsSummary	A summary of perf metrics collected and performance environment info
CPerfSample	Resource representing a single performance measure or data point
CPerfSampleSeries	Resource representing a collection of performance samples (or data points)
CPrimaryStep	Stores rollup test status of multiple steps that were run as a group and outcome of each individual step.
CProjectSettings	Per-project settings for the Tool Results service.
CPublishXunitXmlFilesRequest	Request message for StepService.PublishXunitXmlFiles.
CResultsStorage	The storage for test results.
CScreen
CScreenshotCluster
CShardSummary	Result summary for a shard in an environment.
CSkippedDetail	Details for an outcome with a SKIPPED outcome summary.
CSpecification	The details about how to run the execution.
CStackTrace	A stacktrace.
CStatus	The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC. Each `Status` message contains three pieces of data: error code, error message, and error details
CStep	A Step represents a single operation performed as part of Execution. A step can be used to represent the execution of a tool ( for example a test runner execution or an execution of a compiler)
CStepDimensionValueEntry
CStepLabelsEntry
CSuccessDetail	Details for an outcome with a SUCCESS outcome summary. LINT.IfChange
CTestCase
CTestCaseReference	A reference to a test case
CTestExecutionStep	A step that represents running tests
CTestIssue	An issue detected occurring during a test execution.
CTestSuiteOverview	A summary of a test suite result either parsed from XML or uploaded directly by a user
CTestTiming	Testing timing break down to know phases.
CThumbnail	A single thumbnail, with its size and format.
CTimestamp	A Timestamp represents a point in time independent of any time zone or local calendar, encoded as a count of seconds and fractions of seconds at nanosecond resolution. The count is relative to an epoch at UTC midnight on January 1, 1970, in the proleptic Gregorian calendar which extends the Gregorian calendar backwards to year one
CToolExecution	An execution of an arbitrary tool. It could be a test runner or a tool copying artifacts or deploying code.
CToolExecutionStep	Generic tool step to be used for binaries we do not explicitly support. For example: running cp to copy artifacts from one location to another.
CToolExitCode	Exit code from a tool execution.
CToolOutputReference	A reference to a ToolExecution output file.
