Gradle difference between test and check

My build.gradle is as follows:

group 'groupName'
version 'version'

apply plugin: 'java'
apply plugin: 'idea'

sourceCompatibility = 1.8

repositories {
    . . .
}

dependencies {
    . . .
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

In Grade when doing ./gradlew tasks I receive

Verification tasks
------------------
check - Runs all checks.
test - Runs the unit tests.

What is the difference between these two tasks? The output of ./gradlew check is identical to ./gradlew test.

From what I understand, ./gradle test ⊆ ./gradle check. Is this correct?

The Gradle check task depends on the test task which means test is executed before check is run. The documentation stats that check performs all verification tasks in the project, including test and also tasks plugins add to the project:

If you for example add the checkstyle plugin to your project you can either run its tasks checkstyleMain and checkstyleTest individually or execute a full project verification using check. In this case the tasks test, checkstyleMain and checkstyleTest would be run.
Whereas test always just executes your unit tests.
