feat: unit testcases for increasing coverage

[Sonichigo]

Hey, I’ve added new unit tests to the Go codebase while testing the capabilities of my Keploy AI testing agent. The tests ensure reliable coverage by validating code builds, eliminating flaky tests, and improving overall test stability. Here’s what the AI checks for:

• Ensures new tests build without errors.
• Confirms no flaky tests are introduced.
• Enhances coverage for previously untested areas.

Coverage Breakdown:
Total Coverage Increased: 52.6% to 64.7%

Coverage Before:

Coverage Now:

Command to run for checking:

go test ./... -cover -coverprofile=coverage.out && go tool cover -func=coverage.out | tail -n 1

let me know if there is anything else I can add.
