Test apparatus and test method

A test apparatus comprising:

• a plurality of test units that test a device under test;
• a plurality of housing sections that respectively house the test units therein;
• a plurality of opening/closing sections that are disposed respectively in the housing sections and that expose the test units to an outside of the respective housing section or isolate the test units from the outside;
• and
• a control section that independently controls whether each of the opening/closing sections is allowed to be opened, wherein
• when one of the opening/closing sections exposes a corresponding test unit to the outside while one of the test units is attempting to perform a predetermined operation, the control section prohibits performance of the predetermined operation or a warning section of the test apparatus issues a warning.

A test apparatus comprising:

• a plurality of test units that test a device under test;
• a plurality of housing sections that respectively house the test units therein;
• a plurality of opening/closing sections that are disposed respectively in the housing sections and that expose the test units to an outside of the respective housing section or isolate the test units from the outside;
• a control section that independently controls whether each of the opening/closing sections is allowed to be opened;
• a first selecting section that enables selection of one of the plurality of test units to be exposed to the outside;
• and
• a second selecting section that enables reselection of the one of the plurality of test units to be exposed to the outside, wherein
• if the test unit selected via the first selecting section matches the test unit selected via the second selecting section, the control section allows the test unit selected via the first selecting section to be exposed to the outside or stops a supply of power to the test unit selected via the first selecting section.

A test method comprising:

• first selecting whereby a test unit, from among a plurality of test units that test a device under test, is selected to be exposed to an outside of a housing section of the test unit;
• second selecting whereby the test unit is reselected to be exposed to the outside;
• and
• if the test unit selected during the first selection matches the test unit selected during the second selection, judging that the test unit selected during the first selection is to be exposed to the outside or stopping a supply of power to the test unit selected during the first selection;
• and
• if it is judged that the test unit selected during the first selection is to be exposed to the outside, allowing the test unit selected during the first selection to be exposed to the outside.
