Australia and South Africa are bidding to win the World Test Championship at Lord's this week

This week's World Test Championship final between Australia and South Africa at Lord's is the longer format's showpiece.

The fixture also represents an opportunity to celebrate international cricket's historic, and most romanticised, form of the game.

For the majority of its 148-year life, Test cricket has been treasured as the pinnacle of the sport, but over the past two decades its popularity has diminished in some countries.

The growth of shorter formats, and especially T20, has played a part and for some national boards Test cricket is seen as a financial millstone amid poor attendances and declining interest.
