Testing Type: Integration Testing, Definition of
Integration Testing
As it name suggest Integration which mean integrate the
modules or units together and then perform the testing for all modules
together in a flow of data. This is called integration testing. Integration testing mean combined
all the units of software together and execute the test cases on them to confirm
that after integration of them they are working fine without any issues or
error
We can call
it ‘String Testing’ and also the ‘Thread Testing’.
Requirement of Integration Testing: In starting developer done the work/code for
units or modules. Then after they combined the units and sent the modules or
project for testing. So to confirm that units are integrated properly and integrated
module is working properly and showing correct result, so this is the need of
integration testing.
Test Cases for Integration Testing: Integration test
cases are the different to another test case. Like we have module for login,
add record and view record. Here first test cases will be created for login
unit then add record page and then view record page. Like a flow of data need
to be tested, is it in correct way and in correct and proper direction.
Strategies of Integration Testing: There are mainly
there are two types of integration testing:
i.
Big Bang Strategy – In this
strategy all units are combined at once and tested at once.
ii.
Incremental Strategy – It is also
divided into more three parts:
a. Top down strategy: Start integration from top to down and as
well as testing.
b. Bottom Up Strategy – Start integration from bottom to top and as
well as testing.
c. Sandwich Strategy – This is combination of above both
strategies. Mean combination of top down strategy and bottom up strategy.
Process of Integration Testing:
i.
First Create or develop the Integration
Test Plans.
ii.
Design the test cases, scenarios and
steps for integrations testing.
iii.
Executing the test cases, finding bug and
create report and reporting to developers.
iv.
Regression and Retesting the bugs.
v.
Follow the Step iii and iv till the all
bug are not fix and project become the issue free.
