S1, configuring access path classification of a distributed database.
The access path classification comprises non-distributed core direct access, non-distributed core access distributed core, distributed core access non-distributed core and distributed core cross-regional center access.
For example, the customer account A data is distributed in a Beijing center database, the customer initiates a non-downed transaction involving the account A in the Wuhan, the corresponding non-distributed core direct access classification, the customer account A data is located in the Beijing center, the customer initiates a downed transaction involving the account A in the Wuhan, the corresponding distributed core access non-distributed core classification is called in the process, the customer account A data is located in a current core, the account B data is located in a distributed core of the Wuhan center, the corresponding non-distributed core access distributed core classification is called in the transfer transaction involving the account A to the account B initiated in the Beijing, the customer account A data is distributed in the Beijing center database, the customer initiates a distributed downed direct access classification of the account A in the Beijing center, the customer account A data is distributed in the Beijing center, the account B data is distributed in the Beijing center, the customer initiates a transaction involving the Beijing to the account A (both downed transactions) corresponding distributed cross-core region center access classification.
S2, configuring transaction scene classification of the distributed database.
The transaction scene classification comprises a common query class, a complex query class, an online consumption class, an online presentation class, a consumption class, a withdrawal class, a transfer class and a maintenance class.
Of course, according to the actual use mode and application environment of the distributed database, the transaction scene classification can be adaptively adjusted, and the main function of the transaction scene classification is to distinguish test disturbance used for testing, so that correct and effective test disturbance can be selectively executed in the testing process.
S3, setting background pressure of the nonfunctional test. Specifically, the duty ratio and average response time of each transaction of the distributed core in a general business day service scene can be obtained to form the background pressure of the nonfunctional test.
S4, setting a corresponding test disturbance set according to the transaction scene classification, wherein the test disturbance set comprises one or more test disturbances, and the test disturbances comprise path labels corresponding to the access path classification.
The test disturbance can include abnormal conditions such as downtime (primary node, secondary node), process stop, process suspension, network card disabling and the like which have great influence on the distributed database, and can also be any other items which need to be tested, such as multiple login errors of users, external network attacks and the like.
Different test perturbations may be combined to form a test perturbation set corresponding to a transaction scenario classification, i.e., an important perturbation that can have an impact (or is considered likely to have an impact) corresponding to a particular transaction scenario classification. For other disturbances with insignificant effects, excluding the set, the running calculation pressure during testing can be reduced without affecting the test results.
On the other hand, by adding the path label to the test disturbance, the test disturbance in the set has the corresponding attribute of the access path and the transaction scene, and the more targeted nonfunctional test can be realized.

Preferably, the main items to be tested of the distributed database comprise computing node cluster effectiveness, data node master-slave copy fault effectiveness, global traffic management node master-slave switching effectiveness, management node cluster effectiveness and disaster recovery switching effectiveness.
S6, loading background pressure, and selecting a corresponding test disturbance set according to the transaction scene classification to which the item to be tested belongs.
Corresponding to different test items, corresponding access paths and transaction scenes are selected, and usable test disturbance is obtained through matching. Preferably, when a plurality of test disturbances exist, the test can be performed sequentially and respectively, and the comprehensive test of the plurality of test disturbances can be applied simultaneously at a time.
S7, setting an access path for testing, and selecting matched test disturbance from a test disturbance set according to the path label.
Preferably, the test disturbance obtained by matching may be one or a plurality of different test disturbances, and the test disturbance should be selected as the matching test disturbance as long as the matching relationship of the path labels is met.
S8, performing nonfunctional testing by using testing disturbance, wherein the method specifically comprises the following steps:
s81, stably operating the item to be tested under the background pressure;
S82, introducing test disturbance, recording a working log under the test disturbance, and when each test disturbance exists, selecting to introduce each test disturbance one by one or synchronously introducing all test disturbance;
S83, discharging test disturbance, and judging whether the item to be tested returns to stable operation.
For example, for a computing node cluster availability project, selecting a test disturbance that is downed may perform the steps of:
1) Initiating scene pressure, using a pressure-generating tool to generate pressure according to the capacity proportion of the business scene of a common business day, operating for 5 minutes after tps is stable, and normally processing on-line business;
2) The node is down, and a command is executed, wherein the command is a bond, the transaction error rate, the processing capacity, the response time and the host resource condition in the scene are observed, and the scene is continuously operated for 5 minutes after tps is recovered;
3) Starting a computing node process date,/dbstart;
4) All the fault machines are recovered to be finished, and the online service is normally processed.
