The insertAdjacentHtml method takes two arguments. The first argument is a string that specifies the position of the inserted element. The second argument is a string containing the HTML to be inserted.
For the first argument, pass the string "beforeend" to insert the new element as the last child of targetInputContainer.
For the second argument, pass your HTMLString variable.
You should pass the string "beforeend" as the first argument to insertAdjacentHTML.
assert.match(addEntry.toString(), /insertAdjacentHTML\(\s*('|")beforeend\1/);
You should pass your HTMLString variable as the second argument to insertAdjacentHTML.
assert.match(addEntry.toString(), /insertAdjacentHTML\(\s*('|")beforeend\1\s*,\s*HTMLString\s*\)/);
