я вычитал, что если из аэропорта не выходить, то тест не нужен:
Exceptions to the test requirement on boarding
In these situations, you are also allowed to board the aircraft without a negative test result:
If you have Swiss citizenship or hold a residence permit issued by Switzerland and you have no possibility of getting tested abroad. In this case, you must complete the self-declaration truthfully and, in doing so, confirm that you had no possibility to get tested within a reasonable time or at reasonable expense. If the information you provide is not true, you risk criminal proceedings under the Epidemics Act. You will find the self-declaration at the end of the website under the tab Documents. Please note: The self-declaration only enables you to fly without showing proof of a negative test result. As soon as you are in Switzerland, you must get tested for the coronavirus as quickly as possible. Both a PCR and a rapid antigen test are permissible for this purpose. Should this test be positive, you must immediately go into isolation.
If you need to be transported to Switzerland urgently on medical grounds and you can provide a medical certificate to prove this.
If you are only entering Switzerland for transit purposes and do not leave the airport.
If you have been infected with the coronavirus within the last three months before entering Switzerland and are healthy again. In this case, the relevant medical certificate is required.
If you are unable to have a nose and throat swab on medical grounds. In this case, the relevant medical certificate is required.
