Answer / himanshu soni

Testing can be majorly divided into following types;

1) White Box Testing.
2) Black Box Testing.

White Box Testing: Generally it is performed on the code of
software. To perform white box testing, you have to
understand the logic behind the code.

Black Box Testing: To perform black box testing, you need
not have to understand the logic behind the code. Black box
testing is further divided into sub types, which are as
follows;

a) Functional Testing.
b) System Testing.
i) Usability Testing.
ii) Performance Testing.
1) Load Testing.
2) Stress Testing.

BVT = Build Verification Test (Sometime Build Validation
Test)
BAT = Build Authentication Test

BAT is run before BVT. They are sometimes run together.

BAT is more to prove that a build built correctly, all
files are present and in correct locations, etc.
Sometimes BAT gets into actual installation of build.

BVT then gets into some basic verification of features
that ensure build actually functions at same predefined
basic quality level. Typically breadth, not depth. Its
to prove the build is of enough quality to warrant
spending the time to install it and perform full testing
or for dev purposes. They are also used for maintaining
a minimum quality bar over time, sometimes increasing
coverage through the project cycle. BVT passes are
typically short, often kept to 15 minutes or less for a
given flavor of a build.

Many people also get into BVT+ which is just extended
coverage but would typically not "fail/reject" a build
if the BVT+ cases failed. This is often done as
additional info and to indicate if build is ready to be
put through an extensive full automation pass.

Build Verification Test is a kind of Regression Testing
done on all new builds in order to verify if any existing
or added functionally is broken or not really being
fulfilled by the new build. BVT is usually done by
Developers but can also be done by Testers. During the BVT
the build is compiled ,executed and deployed in the
Development environment .If any problem persist then it
will be fixed and the developers will continue with the
UNIT Test. If the development team is small and if they
don’t have much time to deploy the code then the same can
be done by Testers. But the testers should have little bit
knowledge of some of the tools like Visual Source Safe
which is the Configuration Management Tool for check
in /out of files and the Deployment Process. The process
will differ depending upon the Client or the Web Based
Applications, and also varies according to organizations
policies.
BVT Automation process verifies whether each and every
modules in the project are Integrated properly or not. Many
of the times the Automation process gets failed during the
Integration of Modules. Automating any process will always
reduce the Time taken for Deployment, for which the
Organization should spend enough money to setup such
Environment. Since the BVTs are generally run on daily
builds, certain things are necessary to complete the
Automation process successful.



They are



· We need knowledgeable person to write the
verification code. Iit should have the automatic check- in
of the updated files and to verify whether it is the latest
build/ version

· Need high performing hardware systems with enough
space in it to create a backup of the process

· Install all the necessary softwares which are
related to the Deployement Process.

· Setup Internet Connection for those servers to
send E-mail when BVT completes or even if there is any
problem with the build.



Apart from these setup, we have to create the Test Suite
for the BVT Automation Process .



· Create valid Test Cases and spend time in writing
script to diagnose the BVT result.

· Remember to include all or most of the critical
and major Test cases in BVT and make sure they are
sufficient for test coverage

· Do not Include any incomplete Module Test cases
in BVT , which will leads to the failure of test cases

· Update the files with latest build
number.Automated Test Suite should be maintained by
Developers team with updated test cases for any new stable
Module.

· Automate all the build processes, since Manual
interference increases the possibility of Failure.Eg:
Starting from the Test Suite creation till sending the BVT
results to the team members

· Create the results log file and verify which test
cases are giving positive reply whenever any new features
are added in the project Add those test cases with the
test suite.

· Try deploying the build in two set of servers
with different operating systems.



Once the build passes the BVT it is given to the testing
team.The URL link will be sent through e-mail to test in
the QA environment. Incase the build fails the BVT is sent
back to the developers for fixing.
