5. The method according to claim 1 , wherein if the indicator memorized in the electronic device indicates that said at least one self-test corresponding to the indicator is optional, then
after performing said at least one self-test corresponding to the indicator, the indicator is attributed a state which indicates that said at least one self-test corresponding to the indicator is not optional.
6. The method according to claim 1 , wherein the indicator is overlooked according to:
a security level of the application, or
when the application has been executed for the last time.
7. The method according to claim 1 , wherein said list of applications comprises at least one personal identity verification application, a payment application, a physical access control application, an identity verification application, an electronic signature application, an authentication application, an encryption application, or a decryption application.

wherein the application is configured for determining whether to perform at least one self-test according to a plurality of indicators memorized in the electronic device, each indicator corresponding to at least one self-test,
wherein each indicator indicates whether the at least one self-test corresponding to the indicator is optional, and
if the indicator memorized in the electronic device indicates that said at least one self-test corresponding to the indicator is not optional, then
after performing said at least one self-test corresponding to the indicator, the application is configured for attributing to the indicator a state which indicates that said at least one self-test corresponding to the indicator is optional.
10. The electronic device of claim 9 , wherein said application having been selected is configured to determine whether to perform said at least one self-test.
11. The electronic device according to claim 9 , wherein said at least one self-test is a power-on self-test as defined in the FIPS 140 standard.
12. The electronic device according to claim 9 , wherein the application is configured for determining whether to perform at least one self-test according to whether the electronic device communicates with the reader in contact mode or contactless mode.
13. The method according to claim 9 , wherein if the indicator memorized in the electronic device indicates that said at least one self-test corresponding to the indicator is optional, then
after performing said at least one self-test corresponding to the indicator, the application is configured for attributing to the indicator a state which indicates that said at least one self-test corresponding to the indicator is not optional.
14. The method according to claim 9 , wherein the indicator is overlooked according to:
a security level of the application, or
when the application has been executed for the last time.
15. The electronic device according to claim 9 , wherein said list of applications comprises at least one personal identity verification application, a payment application, a physical access control application, an identity verification application, an electronic signature application, an authentication application, an encryption application, or a decryption application.
