Test cases are getting skipped after upgrading

[Jagdish Kamble]

I am migrating from Spring boot version 2.1.13.RELEASE to 2.4.2 version.
Along with Spring version I have also upgraded the maven plugin version as
follows:

Old:
    <maven-checkstyle-plugin.version>3.1.0</maven-checkstyle-plugin.version>

<maven-dependency-check-plugin.version>4.0.2</maven-dependency-check-plugin.version>
    <maven-frontend-plugin.version>1.7.6</maven-frontend-plugin.version>
    maven-gmaven-plugin.version>1.6.3</maven-gmaven-plugin.version>
    <maven-jacoco-plugin.version>0.8.5</maven-jacoco-plugin.version>
    <maven-pmd-plugin.version>3.12.0</maven-pmd-plugin.version>
    <maven-spotbugs-plugin.version>3.1.12.2</maven-spotbugs-plugin.version>

<maven-spring-cloud-contract-plugin.version>2.1.3.RELEASE</maven-spring-cloud-contract-plugin.version>
    <maven-surefire-plugin.version>2.22.2</maven-surefire-plugin.version>


New :
    <maven-checkstyle-plugin.version>3.1.1</maven-checkstyle-plugin.version>

<maven-dependency-check-plugin.version>6.0.4</maven-dependency-check-plugin.version>
    <maven-frontend-plugin.version>1.8.0</maven-frontend-plugin.version>
    <maven-gmaven-plugin.version>1.12.1</maven-gmaven-plugin.version>
    <maven-jacoco-plugin.version>0.8.6</maven-jacoco-plugin.version>
    <maven-pmd-plugin.version>3.14.0</maven-pmd-plugin.version>
    <maven-spotbugs-plugin.version>4.2.0</maven-spotbugs-plugin.version>

<maven-spring-cloud-contract-plugin.version>3.0.0</maven-spring-cloud-contract-plugin.version>
    <maven-surefire-plugin.version>3.0.0-M5</maven-surefire-plugin.version>


*After upgrading, my test cases are not getting executed.it doesn't throw
any error.It just print below lines:*



*[INFO] Results:[INFO] [INFO] Tests run: 0, Failures: 0, Errors: 0,
Skipped: 0*

Before upgrading it is to print below:
[INFO] Results:
[INFO]
[INFO] Tests run: 69, Failures: 0, Errors: 0, Skipped: 0

Any guidance about the above issue is appreciated.

Thanks
