There are 5 levels of testing.
1) Unite level testing
2) Module level testing
3) Integration level testing
4) System level testing
5) User acceptance level testing
1) Unit level testing
If one performs testing on a unit then that level of testing
is known as unit level testing. It is white box testing
usually developers perform it.
Unit: - It is defined as a smallest part of an application.
2) Module level testing
If one perform testing on a module that is known as module
level testing. It is black box testing usually test
engineers perform it.
3) Integration level testing
Once the modules are developing the developers will develop
some interfaces and integrate the module with the help of
those interfaces while integration they will check whether
the interfaces are working fine or not. It is a white box
testing and usually developers or white box testers perform it.
The developers will be integrating the modules in any one of
the following approaches.
i) Top Down Approach (TDA)
In this approach the parent modules are developed first and
then integrated with child modules.
ii) Bottom Up Approach (BUA)
In this approach the child modules are developed first and
the integrated that to the corresponding parent modules.
iii) Hybrid Approach
This approach is a mixed approach of both Top down and
Bottom up approaches.
iv) Big Bang Approach
Once all the modules are ready at a time integrating them
finally is known as big bang approach.
STUB
While integrating the modules in top down approach if at all
any mandatory module is missing then that module is replace
with a temporary program known as STUB.
DRIVER
While integrating the modules in bottom up approach if at
all any mandatory module is missing then that module is
replace with a temporary program known as DRIVER.
4) System level testing
Once the application is deployed into the environment then
if one performs testing on the system it is known as system
level testing it is a black box testing and usually done by
the test engineers.
At this level of testing so many types of testing are done.
Some of those are
a) System Integration Testing
b) Load Testing
c) Performance Testing
d) Stress Testing etc….
5) User acceptance testing.
The same system testing done in the presents of the user is
known as user acceptance testing. It s a black box testing
usually done by the Test engineers.
