The most important aspect of heating liquids in a test tube is to never look directly into the mouth of the test tube, as liquid may spurt out and come into contact with your eyes or face. However, if you are wearing plastic safety glasses, the substance may not harm you, depending on the type of substance you are heating.
It depends on what you are doing, you should be sure to follow instructions carefully and be sure to take proper safety precautions

Before heating it, you should check the test tube for damage (scratches or cracks), and not use one that isn't perfect. You should also wear safety glasses (to protect your eyes in case the test tube explodes, which happens sometimes, even when heating water). If you are heating something that could react violently, you should use a blast shield (thick piece of clear plastic).

The mouth of the test tube should be pointed away from yourself and others to prevent any splashes or fumes from coming into contact. This is important for safety measures and to avoid any potential accidents during the heating process.
When heating a test tube over a Bunsen burner, you typically use heat-resistant gloves to handle the test tube, a test tube holder to hold the test tube, and a Bunsen burner for heating. It's also important to have a heat-resistant mat or pad to place the test tube on while heating.

You should always point the end of a test tube away from yourself when heating it to prevent any potential splattering or spattering of the contents towards you. This is a safety precaution to minimize the risk of burns or injury from hot liquids or materials.
To test a dryer heating element, you can use a multimeter to check for continuity. Disconnect the dryer from power, remove the heating element, and test for continuity using the multimeter. If there is no continuity, the heating element is faulty and needs to be replaced.
A beaker is better for heating compared to a test tube because it does not break up easily.
