We can measure the elapsed time of executing each table.

when input is⇓ story test fixture check plain test configure settings elapsed show 'simple sample' check count 0 increment 'sample fixture' has good stuff check count 1 configure settings elapsed show simple sample check count 0 elapsed: 0.001 increment elapsed: 0.003 sample fixture has good stuff elapsed: 0.004 check count 1 elapsed: 0.005

configure settings elapsed show 'simple sample' check count 0 increment 'sample fixture' has good stuff check count 1

then output is

configure settings elapsed show simple sample check count 0 elapsed: 0.001 increment elapsed: 0.003 sample fixture has good stuff elapsed: 0.004 check count 1 elapsed: 0.005
