Normal examples are verified as usual: >>> 1+3 4 But if you put '# random' in the output, it is ignored: >>> 1+3 junk goes here... # random >>> 1+2 again, anything goes #random if multiline, the random mark is only needed once. >>> 1+2 You can also put the random marker at the end: # random >>> 1+2 # random .. or at the beginning. More correct input is properly verified: >>> ranfunc() 'ranfunc' ranfuncrrrrrrUs 6 9rcdS)aA function where we ignore the output of ALL examples. Examples: # all-random This mark tells the testing machinery that all subsequent examples should be treated as random (ignoring their output). They are still executed, so if a they raise an error, it will be detected as such, but their output is completely ignored. >>> 1+3 junk goes here... >>> 1+3 klasdfj; >>> 1+2 again, anything goes blah...
