Software testing
is a crucial element of the Software Development Lifecycle. In this write-up we
will go through some of the common questions that you may be asked at the time
of a software testing interview. Keep in
mind that the answers provided here are just for guidance. You have complete
liberty to modify and expand the answers if you want.
What is the procedure to create a test script?
Ans: 1st Step –
Completely understand the Application Under Test (AUT)
i)
Read the requirement doc
carefully.
ii)
If there is no requirement doc,
try to get an idea from the point of references like a previous or old version
of the app, screen shots or wire-frames.
2nd Step –
After you understand the requirement, make a list of what portions of this app
have to be tested. This means, in this step you have to focus on “What to
test”. At the end of this step you will come up with a list of test setups.
3rd Step – In
this step you have to concentrate on “How to test”. Here you have to write down
the detailed steps involved in testing a particular feature, test data to enter
and the expected outcome.
Once these three
steps are completed, you can proceed with testing.
What the types of test techniques and what are they
used for?
Ans: Uses of test
techniques a) To help make out defects
b) To trim down the number of test cases.
Different test technique
- Boundary Value Analysis – used to scrutinize the system behavior while analyzing the boundary value in software testing.
Equivalence partitioning – used to cut down the numbers of test cases by classifying sets of
data that are different and executing only 1 test from each set.
All
Pairs Testing or Pair-wise – used to lessen the
number of test cases while escalating the exposure of feature combo.
State Transition Testing – used to confirm allowed and disallowed states and conversion from
one state to another by different input data.
What
are the fields to be included in a bug report?
Ans:
Fields to be included in a good bug report are:
- One unique ID
- Defect description
- Steps to re-create – how to arrive at the defect, exact test data, defect- detection time, other info that will help re-address the problem.
- Module/ section of the app
- Screenshot
- Severity
- Responsible QA – follow up regarding bug fixing.
Define
white box testing and black box testing?
Ans: In White
Box Testing the tester can check inside the process and authenticate the data
prior to the end outcome. Validation steps may be required in white box
testing. On the other hand, Black Box Testing examines the functions of an app
without peering inside the process. This test method can be used at entry level
software testing – unit, system, integration and acceptance. The software
testers cannot see inside the process.
They can only see the output
Briefly
describe the process involved in mobile app testing?
Ans: - Verify if the
app functions properly with multiple devices and carriers
-
Check the serviceability of the
features in a mobile screen
-
Testing on different platforms
like iOS and Android
-
Installing, Uninstalling, testing functions,
launching the application with or without networks
-
Internet connectivity - 2G, 3G. WiFi, etc.
What
types of testing are important for web testing?
Ans: Types of testing
important for web application testing are:
a)
PerformanceTesting – It is the process of finding out the
speed or efficiency of a computer, network web software program. This process
involves quantitative tests performed in a lab, like calculating the response
time, etc.
b)
Security Testing – It is a type of
non-functional testing that is performed to verify whether the app or product
is secured or not. It verifies if the application is susceptible to attacks
like unauthorized access or hacking
Hoping that this post will benefit software testing professionals who wish to get selected in giant IT companies.
