Test Cases for Triangles

We have studied the properties of various triangles in school. Let us apply those properties to test a triangle today.

A triangle is made of three sides (and three angles of course). Let us assume that the vertices are A, B and C, and corresponding sides are a, b, c.

Test cases follow:

1. Enter 0, a, b. No triangle is formed.
2. Enter 1, 2, 4. No triangle is formed because for a valid triangle a+b>c, b+c>a, c+a>b.
3. Enter angles A, B, C. The sum of the angles should be 180 degrees.
4. Enter a, a, a. Valid equilateral triangle.
5. Enter a, a, b. Valid isosceles triangle.
6. Enter angles A, B, C. If any of the angles is 90 degrees and the sum is 180 degrees, it is a right angle triangle.
7. Enter angles A, B, C as 90, 90, 0. The sum of angles is 180 degrees, still the triangle cannot be formed.
8. Enter negative value for a side, e.g. -1, -1, -1. Invalid input.
9. Enter character value for one of the sides, e.g. a, 2, 2. Invalid input.

Critical Bugs in a Web-based Banking Product

Banking products are highly secured. The money transaction, precise calculations, updation at the backend (i.e. database), clear instructions about the steps to be performed for a certain action, security, 24X7 availability of servers, performance and usability are highest priority when it comes to design and develop a banking product.

Testing Interviews

Testing interviews are very tricky. It comprises of evaluating your communication skills, behavioral aspects, attitude, aptitude, customer focus, sensitiveness towards end user's perspective, capability to understand complex and varied nature of documents, capability to produce clear and concise reports, knowledge of processes and standards; apart from the other technical skills.

Technical skills really depend on the job requirement. In general, software companies expect you to be aware of Operating Systems, Databases, Web Servers, App Servers etc. I'm reiterating that the job requirement can vary from project to project, company to company. If you are in niche domains such as mobile testing, network protocol testing or mobile chipset testing you need the domain knowledge well. With certain products domain knowledge also helps a lot. For example, for a product in banking and financial domain, you need some understanding of the domain. It helps in understanding the workflow and the terminologies used in the product.
