Test cases in case I come back to this:

	test( 'Skip <nowiki>:{{unblock}}', () => {
		const wikitext = `Test <code><nowiki>:{{unblock|reason=Your reason here ~~~~}}</nowiki></code> Test`;
		const appealReason = `Your reason here `;
		expect( () => {unblockReview.getLeftHalfOfUnblockTemplate( wikitext, appealReason );} ).toThrow( Error );
		expect( () => {unblockReview.getLeftHalfOfUnblockTemplate( wikitext, appealReason );} ).toThrow( "Searching for target text failed" );
	} );

---

	test( '<nowiki> in front of {{Unblock}}', () => {
		const wikitext =
`<nowiki>{{unblock|reason=Test1}}</nowiki>
{{unblock|reason=Test1}}`;
		const paramsAndReason = `Test1`;
		const acceptDeclineReason = `Insufficient. ~~~~`;
		const acceptOrDecline = `decline`;
		const expected =
`<nowiki>{{unblock|reason=Test1}}</nowiki>
{{unblock reviewed|decline=Insufficient. ~~~~|1=Test1}}`;
		expect( unblockReview.processAcceptOrDecline( wikitext, paramsAndReason, acceptDeclineReason, DEFAULT_DECLINE_REASON, acceptOrDecline ) ).toBe( expected );
	} );

	test( '<nowiki>: in front of {{Unblock}}', () => {

		const acceptOrDecline = `decline`;
		const expected =
`<nowiki>:{{unblock|reason=Test1}}</nowiki>
{{unblock reviewed|decline=Insufficient. ~~~~|1=Test1}}`;
		expect( unblockReview.processAcceptOrDecline( wikitext, paramsAndReason, acceptDeclineReason, DEFAULT_DECLINE_REASON, acceptOrDecline ) ).toBe( expected );
