Description: 

A new method for Kernel tests, KernelTestBase::installSpecificConfig() allows installing specific default configuration from modules. Previously, it was only possible to install none or all of a module's default configuration. This often means that a kernel test is installing configuration items it does not need.

Previously:

class MyKernelTest extends KernelTestBase {

  protected function setUp(): void {
    // Install all of the config from modules foo and bar.
    $this->installConfig(['foo', 'bar']);
  }

}

Now:

class MyKernelTest extends KernelTestBase {

  protected function setUp(): void {
    // Install all of the config from module foo.
    $this->installConfig(['foo']);
    // Install only one particular config from the module bar.
    $this->installSpecificConfig('bar', 'node.type.bar_node_type');
  }

}
