getting NoClassDefFoundError: javax/servlet/ServletException error while running sprringboot test cases

Question

I am using the following dependency for spring test and it is getting failed to load the application context while running.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.3.RELEASE</version>
    <relativePath/> 
</parent>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <!--<version>2.1.8.RELEASE</version>-->
        <scope>compile</scope>
        <!--<scope>compile</scope>-->
    </dependency>

Inside some of the cases I am using

@Autowired
    AutowireCapableBeanFactory beanFactory;

and getting the mentioned error while running test cases

java.lang.NoClassDefFoundError: javax/servlet/ServletException

You miss the servlet api in your claspath. Add:

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
    <scope>test</scope>
</dependency>

to your pom
