Overview

Product summary

Review the store description, core capabilities, and common use cases.

Test File Injector lets you inject test files directly into file upload fields on any website, without opening a file picker or manually selecting a file each time.

Built for developers and QA engineers who repeatedly test file upload functionality.

How it works

Click on any file upload field and Test File Injector intercepts it, showing you a small modal where you can choose what to inject. Confirm, and the file is placed directly into the field, ready to submit.

Two modes

1. Generated files: Instantly create a PDF, CSV, or PNG at a precise target size. Useful for testing size limits, validation logic, or server-side processing without needing real files on hand.
