## What is TesterKey?

TesterKey is a custom keyboard for software testers and developers for testing apps and websites on mobile devices. It enables testing with more complex input than default mobile keyboards provide and also saves a lot of time when using randomised and saved input values.

Features:
* Easily switch between default iOS keyboard and TesterKey to fill forms with your pre-saved test data like name, address email etc.
* Generate randomised form values 
* Enter long self-descriptive test strings aka. counterstrings e.g. 2*4*6*8*11* where the last number tells the character position of the last * or your own custom delimiter.
* Enter foreign language texts with a single tap
* Generate random numbers and ASCII/Unicode strings
* Lorem Ipsum generator
* Save multiple profiles for testing many apps with specific data
* Load test input values from your own hosted external configuration file so that data can be stored and prepared outside of the mobile device
* Shortcut keys F1,F2,F3 for entering text you frequently need to type
* Quickly enter interesting number for testing such as 2 to the power of 64
* Shortcuts for testing applications against cross-site scripting and sql injection
* Generate long strings of W characters for testing field layouts with the widest character (capital W)
* Enter combinations of accented characters such as ÄĀá with a single tap

TesterKey does not collect or send any data you type on our keyboard. Also the values you store in the app's settings are only stored on your device.

NB! iOS restricts that password field values cannot be filled by custom keyboards and iOS default keyboard will replace TesterKey when you type in the password. Use the keyboard's copy password to clipboard function to quickly paste the password with the custom keyboard to speed up filling password form fields.
