Hypothesis testing is what is says on the tin – testing a hypothesis, where a hypothesis is a theory about a given situation. For example, you might have a coin that you suspect is biased as coin tossing seems to be favouring heads over tails. You might like to test the hypothesis that the coin is biased in favour of heads – this would be hypothesis testing.

In order to test your hypothesis mathematically, you must first be very clear about what you are testing. This involves stating a null hypothesis and an alternative hypothesis.
