assertThat(xml.contains("<name>Sample Plugin</name>")).isTrue();

assertThat(xml.contains("<name>Sample Plugin</name>")).isTrue();

assertThat(xml).contains("<name>Sample Plugin</name>");

This can be covered by the AssertThatStringContains rule.

[Pankraz76]

then might be just an alignment of internal recipe orchestration.
