incrby_test.go - Overview​

This file contains test cases for the INCRBY command in the Ironhawk package. It tests various scenarios, including incrementing existing integer keys, negative increments, non-existent keys, maximum and minimum integer values, and type errors.

Detailed Documentation​

TestINCRBY Function​

Purpose: Tests the functionality of the INCRBY command.

Parameters:

  • t (*testing.T): Testing object for running the test.

Returns:

  • None

The function defines a set of test cases, each consisting of a name, a series of commands to execute, and the expected results. It then iterates through these test cases, executing the commands against a local Redis client and verifying that the actual results match the expected results.

testCases Variable​

Purpose: Holds a slice of TestCase structs, each representing a specific test scenario for the INCRBY command.

Type: []TestCase

Each TestCase struct contains:

  • name (string): A descriptive name for the test case.
  • commands ([]string): A slice of strings representing the commands to be executed in sequence.
  • expected ([]interface{}): A slice of interfaces representing the expected responses from the server after each command.

The test cases cover scenarios such as:

  • Incrementing existing integer keys.
  • Incrementing by negative values.
  • Incrementing non-existent keys (which should create them).
  • Incrementing at the boundaries of int64 (maximum and minimum values, testing rollover).
  • Attempting to increment a string value (expecting a type error).
