This document discusses Indium Software's approach to mobile API testing. It defines an API as a software-to-software interface that allows applications to communicate without user intervention. The document outlines how mobile apps use APIs to retrieve data from backends via standard protocols like HTTP and REST. It also describes Indium's process for setting up a test environment and carrying out functional, performance, and security testing of mobile APIs on Android and iOS platforms.

Define API
2
 API stands for
 An API is a software-to-
software interface, not a user
interface.
 With APIs, applications talk to
each other without any user
knowledge or intervention.
 Implemented by writing
function calls in the program.
 API s has libraries from the
Providers.

How It Works ?
3
 Google Maps has one of the most popular
APIs on the internet and provides a good
example of their power.
 Face book allows developers through an API
to create ‘apps’ that have become one of the
main sources of entertainment on Face
book.

Mobile API
4
 A mobile application will
talk to its backend APIs via
standard protocols.
 Principles- HTTP and REST
with Data Format- XML and
JSON respectively
 APIs may either be your own
or from any number of 3rd
parties
 which can be integrated by
calling them directly from
your application, or indirectly
via your API backend

Challenges
8
Challenge 1: No
proper documents
were provided
Solution :
Based on the KT
session, gathered
the information to
work on the
application
Challenge 2:
Timelines
Solution:
Individually shared
the platform
Challenge 3: New
feature Guidelines
were not provided
Solution:
Get the knowledge
of new features
from the
developers through
skype
Challenge 4:
Verifying and
validating the
output in different
system is little
difficult for testers.
Solution: In-depth
understanding of
functional behavior
and sharing among
the team to have
deeper understand
of same
functionality on
different system.
Challenge5:
Exception
handling function
needs to utilized
and used properly.
Solution:Based of
Documentation,
various exception s
has been handled
with its own
exception handling
methods.

In Our Practice
11
 Understand the exact business requirement and priorities it.
 Requirement traceability Matrix is created to provide Input Parameters .
 The Low Level and High Level test cases are documented.
 The Testing Process is carried out once the test case is signed off by Client.
