Functions - Flag Arguments

[jnguyen095]

• Flag arguments are ugly. Passing a boolean into a function is a truly terrible practice. It
  immediately complicates the signature of the method, loudly proclaiming that this function
  does more than one thing. It does one thing if the flag is true and another if the flag is false!
• Method call render(true) is just plain confusing to a poor reader
• Method

render(boolean isSuite)

Should have split the function into two:

renderForSuite() 

and

renderForSingleTest().
