table_test.go - Overview​

This file contains unit tests for the PrepareMetricQueryDeltaTable function, which generates ClickHouse queries for table views based on builder queries.

Detailed Documentation​

TestPrepareTableQuery​

  • Purpose: Tests the PrepareMetricQueryDeltaTable function with various scenarios to ensure it generates the correct ClickHouse queries.
  • Parameters:
    • t (*testing.T): The testing object provided by the Go testing framework.
  • Returns: None

Within TestPrepareTableQuery, there is a struct testCases

  • Purpose: Defines a set of test cases for verifying the PrepareMetricQueryDeltaTable function.
  • Fields:
    • name (string): Name of the test case.
    • builderQuery (*v3.BuilderQuery): The builder query used to generate the ClickHouse query.
    • start (int64): Start timestamp for the query.
    • end (int64): End timestamp for the query.
    • expectedQueryContains (string): A substring that the generated query is expected to contain.

PrepareMetricQueryDeltaTable​

  • Purpose: This function is not defined in this file, but is tested. Based on the test, it seems to take a start time, end time, step interval, and a builder query as input and generates a ClickHouse query string for a table view, presumably for delta metrics.
  • Parameters:
    • start (int64): Start timestamp for the query.
    • end (int64): End timestamp for the query.
    • stepInterval (int64): The step interval for the query.
    • builderQuery (*v3.BuilderQuery): The builder query used to generate the ClickHouse query.
  • Returns:
    • query (string): The generated ClickHouse query string.
    • err (error): An error object, if any error occurred during query preparation. It returns nil if no error occurred.
