How to Test Without a Formal Test Plan?
Testing always requires a formal plan. But there are circumstances where testers need to skip plans to achieve their targets assigned and the tips below will help testers to work without a formal plan.
1) Finding High Level Functions As always high level functions are of central purpose to the site or an application, modify those functions based on the priority frequently according to their significance to a user's ability. Determine the test direction as soon as possible to see changes happening rapid.
2) Test Before Display Before the product is being displayed test it using different browsers and platforms also use designers and developers to review the tests. This is an instant where testers run out of time and they need to test without a formal plan.
3) Concentrate on Ideal Path Actions Testers should assume themselves as users, focus on the ideal path and identify those factors most likely to be used in a majority of user interactions. Get to know about the sections where the user makes a frequent visit, because most of the user doesn't think the same way hence make a set of guess based on user's interest when he visits your website.
4) Focus on Intrinsic Factors Intrinsic factors are internal and it can be fixed only by the tester also the user can do nothing with it. Hence these factors require an immediate attention before the error reflects in the user's end. These errors are time sensitive hence it needs to be fixed without a formal plan.
5) Boundary Test from Reasonable to Extreme The systematic testing of error handling is called boundary testing. Unknown values may choke the system therefore start with all you know when you perform a boundary test. Finding reasonable and predictable mistakes is a better way to perform a progressive boundary test.
6) Good Values Always use valid and current information. Enter in data formatted as the interface requires. Include all required fields all these good values will help testers to make less errors.
7) Reasonable and Predictable Mistakes It is easier for testers to predict errors done based on design especially with interface interpretation. These errors are very common and occur frequently due to complex design in fact it is easy to fix without a formal plan.
8) Extreme Errors and Crazy Inputs Testing for maximum size of inputs, long strings of garbage, numbers in the text fields and text in numeric fields will reduce extreme errors, proceed from most likely to less likely to save time.
9) Compatibility Testing from good to bad It is always good to start a test with the configurations which is more familiar. Therefore when you test a cross platform application begin your testing process with the most used browser and then with least used browser.
10) Expected Bad Values A tester should make sure that an error message pops out each time when some invalid entries are entered in places like online forms. Such test cases don't require a formal plan. A tester can easily give random values to test the application.
