<\/span>1) What is Rest-Assured?<\/strong><\/span><\/h3>\n\n\n\n
Rest Assured is a popular open-source Java-based library developed and maintained by Johan Haleby and widely used for testing Restful APIs.<\/p>\n\n\n\n
<\/span>2) Why should you Use Rest Assured Over Postman for Automated Testing?<\/strong><\/span><\/h3>\n\n\n\n
Both Postman and Rest Assured have their advantages and disadvantages: I choose Rest Assured because it is a Java DSL hence code can be designed in such a way as to maintain reusability, the more the reusability, the lesser the maintenance cost. Scripts can be designed using a behaviour-driven approach or a data-driven approach per the requirements. Reports can be customized but it is not possible in Postman.<\/p>\n\n\n\n
<\/span>3) How does Rest Assured work internally?<\/strong><\/span><\/h3>\n\n\n\nRest assured internally uses Groovy language. Groovy comes with a path expression language called GPath<\/a>. it is used to extract responses and works for both XML and JSON.<\/p>\n\n\n\n
<\/span>4) How to add Rest Assured to a Maven project?<\/strong><\/span><\/h3>\n\n\n\n
To Add Rest Assured in Maven project add below mentioned dependency in pom.xml.<\/p>\n\n\n\n

<\/span>4) How to add Rest Assured to a Maven project?<\/strong><\/span><\/h3>\n\n\n\n
To Add Rest Assured in Maven project add below mentioned dependency in pom.xml.<\/p>\n\n\n\n

<\/span>5) How to send a GET request using Rest Assured?<\/strong><\/span><\/h3>\n\n\n\n
Get is the HTTP method that is used to fetch the information from the server.<\/p>\n\n\n\n

<\/span>6) How to log response in Rest Assured only in the case of an error.<\/strong><\/span><\/h3>\n\n\n\n
User ifError()<\/strong> method. It Logs everything only if an error occurs.<\/p>\n\n\n\n

<\/span>7) How to mask header information in API testing?<\/strong><\/span><\/h3>\n\n\n\n
From Rest Assured version 4.2.0 we can hide header information by blacklisting it so that it will not be shown in the request or response log.<\/p>\n\n\n\n

<\/span>8) How to send multivalue headers in Rest Assured?<\/strong><\/span><\/h3>\n\n\n\n
Rest Assured supports sending multiple header values in the header method.<\/p>\n\n\n\n

<\/span>9) Explain different ways of extracting a single field from a response body.<\/strong><\/span><\/h3>\n\n\n\n
1)Use the Response object<\/strong><\/p>\n\n\n\n
