👉 The word "lineTcpO3Test" means a specific line in an O3 test file, often used for TCP/IP communication tests on AWS Lambda. For example: ``` #!/bin/bash LINE_TCP_O3_TEST_SERVER_CONF="server_name=test.example.com" ``` LineTCPO3Test.server.conf is a YAML file that defines the parameters of a line protocol test run. It contains key-value pairs in this format: 1. `ServerName`: The name of the server being tested. 2. `ProtocolVersion`: The version of the protocol (e.g., TCP/IPv4). 3. `SocketConfigFile`: If set, specifies the file containing the configuration data for connecting to a specific port. 4. `TestType`: Which type of test is being run (e.g., TCP/IP, etc.). 5. `TestParameters`: The parameters used during the test, such as IP addresses, ports, or other details related to the connection. 6. `TlsOptions`: Options for TLS encryption if enabled. 7. `ClientCertificatePath`: Path to a certificate file that should be used for client authentication. 8. `ServerCertificateFile`: If provided, uses the server certificate stored in this location as the key used for client authentication. 9. `TimeoutSeconds`: Time in seconds to wait after successful connection before giving up (e.g., 10). Please note: The actual definition and usage of 'LineTcpO3Test.server.conf' would vary based on AWS Lambda's version.
