Description

Technical Field

[0001] The present invention relates to the technical field of network communication, and in particular to a method for constructing a SAI Thrift automated testing framework. Background Art

[0002] Thrift is a cross-language and cross-platform service deployment framework. It defines RPC interfaces and data types through an interface definition language, and then generates different language codes (supporting C++, Java, Python, PHP, Ruby, Erlang, etc.) through the Thrift compiler. The generated code is responsible for the implementation of the RPC protocol layer and the transport layer. RPC (Remote Procedure Call) is a remote call protocol. Simply put, it enables applications to call remote procedures or services like calling local methods. It can be applied to many scenarios such as distributed services, distributed computing, and remote service calls.

[0003] SAI Thrift is a SAI functional testing framework based on Thrift technology. Figure 1 As shown in the figure, it consists of a server (Test Machine) and a device under test (DUT, Device Under Test). The server's network card is directly connected to the network port of the device under test. The DUT acts as the SAI Thrift test server, and the server Test Machine acts as the client of the SAI Thrift test. The SAI Server Container, also known as the Thrift Test Server, is run on the device under test Switch; a server with multiple INTF network cards installed is used as the Test Machine, also known as the SAIThrift Test Client, and the server interface is physically connected to the device under test; the test PTF script is executed on the SAI Thrift TestClient to test the function and performance of the device under test. The current test device and the test server are interconnected using multiple network ports to perform functional testing of the device. The Test Machine server first remotely calls the SAI external interface on the DUT to configure the Device; the Test Machine server then constructs and assembles the message and sends it to the DUT through the network card; then checks whether the network card has received the message from the DUT. If the message is received, further checks whether the message format meets the expectations, so as to achieve the purpose of testing the DUT message forwarding function.

[0004] In the application practice of SAI Thrift, some test cases require more network ports, which puts forward the requirement of multiple network cards and multiple ports for Test Machine. Test Machine usually uses a server as a test machine, and the requirement of multiple network cards introduces the problem of high server costs. SAI THRIFT test is an exclusive mode for network port resources, which means that the network resources of the server are fully utilized, but the computing and storage resources of the server are wasted. Summary of the invention

[0005] According to an embodiment of the present invention, a method for constructing a SAI Thrift automated testing framework is provided, comprising the following steps:

[0006] Select a network device, define the network device as a test server, and configure a minimized system on the network device;

[0013] Furthermore, the basic container includes: a syncd container, a swss container, and a database container.
