Feature Request: Custom Test Template

[baincd]

I think it would be a nice feature to be able to configure a custom test template. For example, the custom template configuration could look something like

"javaTests.customTemplate": [
  "package {PackageName};",
  "",
  "import static org.assertj.core.api.Assertions.assertThat;",
  "",
  "import org.junit.jupiter.api.Test;",
  "",
  "public class {ClassUnderTest}Test {",
  "",
  "	private {ClassUnderTest} classUnderTest;",
  "",
  "	@BeforeEach",
  "	public void setup() {",
  "		classUnderTest = new {ClassUnderTest}(serviceProperties);",
  "	}",
  "",
  "	@Test",
  "	public void testSomething() {",
  "		assertThat(2+2).isEqualTo(5);",
  "	}",
  "}",
]

There would need to be some placeholders that would be replaced, such as

• {PackageName}
• {ClassUnderTest}
• {ClassUnderTestAsVarName} (the class under test name, but with the first letter lower case).
