The document outlines 5 major challenges of API testing: 1) Setting up the testing environment with the needed API parameters, 2) Sequencing API calls in the proper order, 3) Managing API versioning as systems evolve, 4) Addressing the near-infinite use cases of APIs, and 5) Validating parameters via API requests. It recommends adopting a modern API testing approach that utilizes leading tools for API testing automation and leverages experience testing applications at various layers to execute successful API testing.

API Versioning
01
Setting up of testing environment with the most needed set of API
parameters and running it successfully is one of the critical
challenges of API testing. It is essential to start combining application
data with API tests to ensure API performs in the way as expected
over set of known configurations.
Sequencing of API Calls
02
There is a necessity that API calls must appear in a specific order to
test them effectively. This usually creates a typical problem for the
testing teams. Moreover, API sequencing becomes even more
difficult while working with multi-threaded applications or other
complicated applications.
API Versioning
03
Typically, versioning is also a primary cause of rising complexity in API
testing. Most systems have a degree of depreciation, that should be
managed by an API with the help of versioning. The API must identify
missing values and allocate some default value to allow the old
version to work.
Complexity with Use Cases
04
API testing specifically follows a different approach to testing. APIs
being a central hub of logic and gateway to data for interfacing
applications, the use cases are near-infinite in API testing. Therefore,
the number of required tests rapidly exceeds the competences of
QA responsible for test case design.
Parameter Validation
05
API Testers may also face problems with respect to validating
parameters via API requests. Testers need to make sure that all
parameter data use the same string or numeric data type, meet the
length constraints, confirm to a specified range of values and should
fit other test criteria.
To overcome the above challenges, a modern API testing approach
should be adopted which consists of:
TestingXperts is proficient in a wide range of API protocols such as
XML, SOAP, JSON, REST, Gdata, YAML, ATOM, RSS, and RDF, etc.
