Ability to work after hours or on weekends if a task requires off hours work to minimize impact on clients or end-users. Black box testing can test specific functions or features of the software under test.
For example, checking that it is possible to log in using correct user credentials, and not possible to log in using wrong credentials. Black box testing can check additional aspects of the software, beyond features and functionality. Black box testing can be used to check if a new version of the software exhibits a regression, or degradation in capabilities, from one version to the next.
Regression testing can be applied to functional aspects of the software for example, a specific feature no longer works as expected in the new version , or non-functional aspects for example, an operation that performed well is very slow in the new version.
Testers can identify that a system has a special response around a specific boundary value. For example, a specific field may accept only values between 0 and Testers can focus on the boundary values -1, 0, 99 and , to see if the system is accepting and rejecting inputs correctly.
Many systems provide outputs based on a set of conditions. For example, a health insurance company may provide different premium based on the age of the insured person under 40 or over 40 and whether they are a smoker or not. This generates a decision table with four rules and up to four outcomes—below is an example with three possible outcomes. In some systems, significant responses are generated when the system transitions from one state to another.
A common example is a login mechanism which allows users to authenticate, but after a specific number of login attempts, transition to a different state, locking the account.
If testers identify a state transition mechanism, they can design test cases that probe the system when it transitions states. For example, for a system that locks the account after five failed login attempts, a test case can check what happens at the sixth login attempt. This technique involves testing for common mistakes developers make when building similar systems. For example, testers can check if the developer handled null values in a field, text in a numeric field or numbers in a text-only field, and sanitization of inputs—whether it is possible to submit user inputs that contain executable code, which has security significance.
These are the methods that I personally normally use in my day to day coding life and they have been very beneficial during the past few years. Note that some of these methods are based on the current technology and stack that I use, and so they may or may not be beneficial to everyone.
Your own programming language and stack however should offer something similar to use. Before anything else, we have to be able to identify just what can be black-boxed. Not everything makes sense to generalize.
For example, ForgotPassword might not be modularizable. Sure, you can have a function called ForgotPassword that takes an email as an argument and does its forgot passwordy job.
But can you reuse that same function for other websites? Probably not. That kind of logic belongs to the core business at hand and there would be little value in hiding its complexity. You want to black-box complex functions that don't necessarily change very often and that can stand alone in terms of functionality. Maybe we can't black-box forgetting a password, because the the logic can vary system to system, but we can black box the logic behind sending emails.
Having a function that solely handles email communications and that can be used across many projects is hugely beneficial and can save you much time. Here are a few functions that I personally have generalized:. I can use these functions over and over in various projects without having to worry about how or if they will work. And again, these might be different for you and your type of work.
As a web developer who works on many different websites, these are some of the more common utilities that I require on a day to day basis. You want to make your functions as flexible as possible and account for missing parameters.
If for example, someone doesn't enter the 'directory' in your Upload function, then you'll want your black-box function to default to something that makes sense. If no name is given for a file, then maybe you'll want to auto-generate one instead. A few programming languages allow you to include optional parameters as part of the language, but for the ones that don't however, you can leverage overloading functions.
You want your function to be as robust as possible, but only if it is a realistic use case. You want your black-box functions to be intuitive without too much thought as to how they function or what they do. And as such, you want to make sure that they have a descriptive naming convention and that the corresponding parameters make sense as well.
A well written function should not have to be reread over and over again until its meaning is understood. This for example, is not a clear enough definition. You can't tell off the bat what type of formatting any of the parameters requires. Are you uploading a file url, or a string of bytes, and destination is just as ambiguous. Having full and descriptive names is key for usability. Essentially, you want all of your bases covered when creating generalized and modularized code.
