Detailed Description
The core of the application is to provide a method, a device and equipment for testing a distributed storage cluster, so that the generation process of a large number of test cases of the distributed storage cluster is effectively simplified to improve efficiency.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a testing method for a distributed storage cluster according to an embodiment of the present application, which mainly includes the following steps:
step 1: and acquiring a test case of the function to be tested.
Extracting yaml configuration files from each subdirectory of a pre-created yaml configuration file set to form a yaml configuration file combination, merging the yaml configuration files in the yaml configuration file combination to generate a merged file, and then generating the merged file in advance according to the merged file by using a code generation tool; and each subdirectory of the yaml configuration file set is stored with yaml configuration files corresponding to various cluster characteristics.
In the application, the generation process of the test cases is different from the prior art, that is, instead of writing various cluster feature changes one by a person skilled in the art, the test cases under various cluster feature conditions are generated at one time by using a code generation tool after previously created yaml configuration files are combined and merged. The cluster characteristics are used to describe the cluster environment, such as a number of storage nodes, a number of MONs, a test point distribution location, and so on.
yaml is an intuitive computer-recognizable data serialization format, a programming language for expressing data sequences with high readability and easy interaction with scripting languages. It is similar to xml (a standard universal markup language) data description language, but the syntax is much simpler than xml and can be used as a configuration file.
When generating a test case using yaml configuration files, a yaml configuration file set may be first created, and yaml configuration files corresponding to the various types of cluster features are stored in the respective subdirectories of the yaml configuration file set, respectively. The specific number and content of the yaml profiles in the yaml profile set are selected and set by those skilled in the art, and the embodiment of the present application is not limited thereto. Yaml configuration files under all conditions of the same cluster feature can be stored in the same subdirectory, for example, assuming that there are 50 storage nodes in the cluster, yaml configuration files corresponding to the 50 storage nodes can be stored in one subdirectory.
The yaml profile combination can be formed by taking the yaml profile from each subdirectory. The specific creation method of the yaml profile set varies, as does the number and content of yaml profile combinations that can be made. For each yaml configuration file combination, a merged file can be generated through merging, and a test case is generated through a preset code generation tool. The code generation tool described herein can be implemented by a person skilled in the art by writing a design in an automated testing platform, and the embodiment of the present application is not limited thereto.
Step 2: and executing the test case so as to test the functions to be tested of the distributed storage cluster.
Therefore, in the testing method of the distributed storage cluster provided by the embodiment of the application, simple and easily-written yaml language is used for configuration, and by combining and merging yaml configuration files corresponding to different cluster characteristics, test cases under various testing conditions are generated at one time by using a code generation tool. Therefore, the testing method of the distributed storage cluster greatly simplifies the workload of the test case generation process and improves the efficiency.
The test method for the distributed storage cluster provided by the application is based on the embodiment as follows:
as a preferred embodiment, the yaml profile set is identified with a first identifier; the yaml configuration file in each subdirectory is a replaceable configuration file of the same type of cluster characteristics;
said extracting yaml configuration files from respective subdirectories of a pre-created yaml configuration file set to form a yaml configuration file combination comprises:
extracting a yaml configuration file from each subdirectory of the pre-created yaml configuration file set to form a yaml configuration file combination.
Specifically, the first identifier may be a "%" identifier. In addition, the alternative configuration file means yaml configuration file which can individually configure the cluster features represented by the subdirectory. For example, in the foregoing example, for the sub-directory storing the yaml configuration files corresponding to 50 storage nodes, each of the yaml configuration files is an alternative configuration file, that is, any one of the yaml configuration files taken from the sub-directory may be combined with the yaml configuration files in other sub-directories to form a yaml configuration file.
For the yaml profile set identified with the first identifier, it can generate the number of yaml profile combinations that is the product of the number of yaml profiles in each subdirectory. For example, for the yaml profile set suites/baz, there are 1 yaml profiles a.yaml in its subdirectory suites/baz/a; there are 2 yaml profiles b1.yaml and b2.yaml in subdirectories suites/baz/b; there are 1 yaml configuration files c.yaml in subdirectory suites/baz/c; there are 2 yaml profiles d1.yaml and d2.yaml in subdirectories suites/baz/d; if it is identified by a first identifier, one can get a total of 4 yaml profile combinations:
a.yaml, b1.yaml, c.yaml and d 1.yaml;
a.yaml, b2.yaml, c.yaml and d 1.yaml;
a.yaml, b1.yaml, c.yaml and d 2.yaml;
a.yaml, b2.yaml, c.yaml and d 2.yaml.
As a preferred embodiment, the yaml profile set is identified with a second identifier; the yaml configuration file in each subdirectory is an irreplaceable configuration file with the same cluster characteristic;
extracting the yaml configuration files from the respective subdirectories of the pre-created yaml configuration file set to form a yaml configuration file combination comprises:
extracting all yaml configuration files from the respective subdirectories of the pre-created yaml configuration file set constitutes a yaml configuration file combination.
In particular, said second identifier may be generally set to a "+" identifier. In addition, the non-replaceable configuration file means yaml configuration file which cannot individually configure the cluster features represented by the sub-directory. For example, two yaml configuration files are stored in the subdirectory, and the two yaml configuration files are both partial configuration files of the 1 st test point, and both the yaml configuration files and the partial configuration files need to be used simultaneously to generate a complete test case, and the two yaml configuration files are non-replaceable configuration files. For the aforementioned yaml profile set suites/baz, if it is identified with the second identifier, one gets 1 combination of yaml profiles in total:
a.yaml, b1.yaml, b2.yaml, c.yaml, d1.yaml and d 2.yaml.
As a preferred embodiment, the cluster feature includes any one or any combination of the following:
the method comprises the following steps of test point identification, storage node number, MON number, MDS number and OSD number.
The following describes a test apparatus for a distributed storage cluster provided in an embodiment of the present application.
Referring to fig. 2, fig. 2 is a block diagram illustrating a testing apparatus of a distributed storage cluster according to the present application; the method comprises an acquisition module 1, an execution module 2 and a generation module 3:
the acquisition module 1 is used for acquiring a test case of a function to be tested;
the execution module 2 is used for executing the test case so as to test the functions to be tested of the distributed storage cluster;

It can be seen that, in the testing apparatus of the distributed storage cluster provided in the present application, the test case obtained by the obtaining module 1 is generated in advance by the generating module 3 based on the simple and easily-compiled yaml configuration file. The generating module 3 specifically combines and merges the yaml configuration files corresponding to different cluster characteristics, and generates test cases under multiple test conditions at one time by using a code generating tool. Therefore, the testing method of the distributed storage cluster greatly simplifies the workload of the test case generation process and improves the efficiency.
