Using a Random Binary String Generator in Cross-browser Testing
A random binary string generator can be useful if you're doing cross-browser testing. For example, if your webapp accepts only 0's or 1's as input, then you can write a unit test that runs through binary numbers of various lengths and makes sure the app doesn't accidentally accept other numbers as input. Another interesting use case is combinatorics. If your application needs to randomly selects a certain number of items from a pool of items, then if you create a random binary number, then the positions of all 1's can be used to "pick the item" and all 0's can be used as "don't pick the item". Another use is signal processing, where 1 indicates a high and 0 indicates a low. You can feed binary data of random length into a signal processor and test if it works correctly when it encounters unexpected random input. In the options of this tool, you can specify how many binary digits you need in each binary string and how many results you need. If the string length is one, then you'll simply get a bunch of 1's and 0's in the output.
