You should never point the open end of the test tube when heating liquids toward yourself or others for your own safety. Liquids inside the test tube when heating may release some gases and might affect someone when you point the open end of the test tube to them. when heating the test tubes, position it diagonally and move it slowly sidewards so we can prevent cracking or breaking of the test tubes if directly positioned on fire.

In heating liquids in a test tube why is the test tube move back and forth across the flame?
You should only heat liquids in the wider kind of test tube known as a boiling tube. Using an ordinary test tube often results in rapid local boiling and consequent shooting out of the liquid, which is known as 'bumping'. That said, many people prefer to move the tube around in the flame at first to prevent uneven heating of the contents, and to produce smoother boiling. There is a very small chance that concentrated heating may put stress on a weak spot in the glass and cause it to break.
