Overview:<\/strong><\/p>\n\n\n\n

In the world of technology, Functional testing is a very essential part of every software product when it comes to deliver Quality to the End-Users. Verifying the functionality against the Requirement Specifications is termed as Black Box Testing where the main concern is about to test the behavior of software, unlike White Box Testing which involves testing of source code that is usually done at the unit level.<\/p>\n\n\n\n

Black Box Testing<\/strong> is also known as opaque, functional or behavioral-based testing which can be applied to every level of testing, such as Unit, Integration, System and User Acceptance Testing. Unlike white box testing, it requires no programming skills as the Test Engineers Validates the software functionality without looking into the internal code structure.

In this blog, we will highlight some major techniques of Black Box Testing:<\/p>\n\n\n\n

Equivalence Class Partitioning:<\/strong><\/h4>\n\n\n\n

In equivalence partitioning, input values are divided into certain groups that are expected to exhibit similar behavior. Each and every condition in the particular partition works as same as others. Moreover, it reduces the number of test cases from infinite to finite and is applicable to all the levels of testing.<\/p>\n\n\n\n

For example:<\/strong><\/p>\n\n\n\n

Suppose, we are creating an account for Opencart Site, <\/p>\n\n\n\n

so it asks for multiple information, such as First Name, Last Name, Contact number, etc.<\/p>\n\n\n\n

Let\u2019s assume Contact Number as one of the fields which accept 10 digits number only. So we can partition it into valid(10 digits) ie: 9876543210 & invalid(9&11 digits) ie: 987654321 and 98765432100.<\/p>\n\n\n\n

Boundary Value Analysis(BVA):<\/strong><\/h4>\n\n\n\n

In this technique, we analyze the boundaries of valid and invalid partitions, as the edge of each equivalence partitions is more likely to throw invalid output than the values within the partitions. Every partition has its maximum and minimum values & these values are set as its boundaries. BVA is also applicable to all levels of testing.<\/p>\n\n\n\n

For example:<\/strong><\/p>\n\n\n\n

Taking the above example into consideration, assume the First Name accepts 6-18 characters only.<\/p>\n\n\n\n

Analyze the boundaries ie: <\/p>\n\n\n\n
