refactor: Remove redundant nil check for slice length in dummy_test.go

[clonemycode]

Overview

I forked this project and added lint checks in the CI, using staticcheck to identify this issue.

rollkit/core/execution/dummy_test.go:30:5: should omit nil check; len() for nil slices is defined as zero (S1009)

In Go, len() on a nil slice returns 0. Therefore, explicitly checking if a slice is nil before checking its length (e.g., if s != nil && len(s) > 0) is redundant. This commit removes the unnecessary nil check for executor.injectedTxs in the TestNewDummyExecutor function in , simplifying the condition to if len(executor.injectedTxs) > 0. This change adheres to common Go idioms and improves code readability without altering behavior.

Summary by CodeRabbit

• Refactor
  • Simplified logic for checking if injected transactions are present in tests.

Walkthrough

A test in the dummy executor module was updated to simplify the condition checking the emptiness of a slice. The explicit nil check was removed, and the test now only checks if the slice length is zero, relying on Go's handling of nil slices.

Changes

File(s)	Change Summary
core/execution/dummy_test.go	Simplified the condition for checking if injectedTxs is empty in the test logic.

Poem

In the warren of code where the tests all reside,
A slice check was trimmed, with no need to decide
If nil or just empty—Go knows what to do!
Our test runs more simply, and carrots accrue.

30-32: Simplify slice emptiness check by removing redundant nil check.

In Go, len(nilSlice) is 0, so the explicit nil check is unnecessary. This change makes the test more idiomatic without altering behavior.
