Implementations§

Source§

impl LightProgramTest

Source

pub async fn new( config: ProgramTestConfig, ) -> Result<LightProgramTest, RpcError>

Creates ProgramTestContext with light protocol and additional programs.

Programs:

  1. light program
  2. account_compression program
  3. light_compressed_token program
  4. light_system_program program

Light Protocol accounts: 5. creates and initializes governance authority 6. creates and initializes group authority 7. registers the light_system_program program with the group authority 8. initializes Merkle tree owned by Note:

  • registers a forester
  • advances to the active phase slot 2
  • active phase doesn’t end
