Wireless Testing Interview Questions and Answers


(Continued from previous question...)

What is wireless testing? How do we do it? What are the concepts a test engineer should have knowledge of? How do u classify testing of wireless products?

a1:
Wireless testing having a different approach....It's having its standards & guidelines for application testing. As per as wireless tech. like Brew, J2me .They having there carrier specific testing Procedure including general concepts of testing like types of testing used for testing.....like functional testing, usablity testing etc.

Another thing is important is it PDA application or Mobile application...by keeping this things in mind you have to test...Network availability ,Compatibility, Call,SMS interrupt issues...We have to follow carrier specific checklist & Procedure for testing...


a2:
Wireless testing you can classify into 3 types:
1) Platform testing: To do this testing, tester should have programming knowledge of cpp, java

2) Protocol testing: To do this, tester should have a knowledge of Networking concepts like, making lan connections, read protocol logs in wireshark, ethereal (both are protocol logging tools), all protocol definitions TCP/IP, UDP.. etc etc

3) Application testing: Testing mobile application is almost testing windows applications but bit different. Some basic networking concepts are must. If the application is to be testing in JUnit, then Java knowledge is a must.

a3:
There are number of components in a Wireless set which may need testing:
Base Unit, Radio, Antenna, Cables, Cpe (or mobile unit)
Each of these have certain functionality which needs to be verified and validated.
On top of these there are RF and coverage related testing which is measuring signal strength and Signal to Noise Ratio in different locations of a cell. This is normally achieved by a drive run using a minivan equipped with a receiver on top of the car.
