    Web services have made information availability across platforms easy and convenient for mass audiences. While many developers feel comfortable developing and designing a web service platform, debugging those web services is a different ball game altogether and needs serious attention. Thanks to technological advancements, today we have several automation tools that can test and debug web services quickly and efficiently. Before we start discussing the best web service testing tools available, let's understand web services in detail.

    What Do Web Services Mean?

    A web service is a program that uses HTTP or HTTPS protocols to deliver and receive data over the internet or world wide web. It is platform-neutral, which means it can run on any operating system or with any programming language. For example, data from a Java program in the form of a web service can be accessed by a.NET platform application via an XML/JSON request. Web services, in general, use a set of protocols and standards to transmit data between applications or systems. The two most popular protocols for interacting with web services are SOAP (Simple Object Access Protocol) and REST (Representational State Transfer). Let’s take a look at both the protocols below:

    • SOAP

    SOAP is an ideal choice in scenarios where faster data transfer, rigorous application development, and environment security using multiple tools are the primary concerns. It is essentially a protocol service that exposes business logic through service interfaces. This protocol only supports the XML data format, and requires greater bandwidth and better security for communicating data.

    • REST

    REST is suitable for integration, AJAX implementation, and providing connections for HTTP queries. Unlike SOAP, REST is more of an architectural style that specifies how a client should communicate with the server. REST exposes business logics using URIs or Uniform Resource Locators. It supports various data forms, including XML, JSON, and HTML, and uses less bandwidth.

    Purpose of Web Service Testing

    Web services testing can occur at various stages of the development and maintenance cycle of a software application. Web service testing examines the following:

    • The capacity of the web service to handle exceptions and boundary value conditions for defined functions.
    • Any inconsistencies, errors, and warnings.
    • Expected performance of a program following repairs and updates.
    • Performance of an application by putting it under load testing using various automation tools.

    The following are some of the problems that web service testing aims to address and resolve:

    • Security flaws: Any vulnerability in the web service API allows hackers to get access to the system and attack it.
    • Performance flaws: Measuring web service response times make it possible to assess the end-to-end capabilities before a GUI is implemented. If the response time is too lengthy (slow), code refactoring can be required to improve application performance.
    • Multithreading issues: Suppose the web service or API answer is encrypted and acts as an input for another API. In that case, attackers can decode the API response from the first API before it passes onto the second API. Web services testing can aid in the detection and resolution of such issues.
    • Warning errors: Incorrect errors or warnings to the caller during business logic testing.
    • Functional errors: Any API-related functional flaw, such as whether or not the API response performs the claimed function.
    • Duplicacy flaws: Wasted code, redundant functionality, and flags.
    • Reliability issues: These include difficulty connecting to the API and obtaining a response.
    • Incorrect handling: Checks if valid parameter values were wrongly handled.
