In order to improve the test resource utilance in cloud testing apparatus, can adopting unshared node to the distribution of test assignment, preferential (Non-shared First, hereinafter referred to as dispatching algorithm NSF).NSF dispatching algorithm is once dispatched the test assignment received at interval of a △ t, the cloud test node of specifying due to these test assignments may have repetition, if mean allocation concurrent test number of threads is to each cloud test node, the cloud test node of multiple task sharing then may be caused to reach original concurrent test thread threshold very soon, the execution of more test assignment cannot be supported simultaneously, have impact on the test assignment concurrency of cloud testing apparatus, for this reason, the unshared cloud test node of preferential use, shared cloud test node can be made can to support more test assignment simultaneously.Concrete, NSF dispatching algorithm comprises following step:
First, the cloud test node that each test assignment received in the △ t time is specified is divided into respectively shared cloud test node and unshared cloud test node two node listings;
Secondly, following steps are performed for each test assignment:
One is respectively to the descending sort according to available concurrent test number of threads of two node listings of this test assignment;
Two is successively to the cloud test node distribution concurrent test number of threads in the list of unshared cloud test node, the concurrent test number of threads that each cloud test node distributes is its current available concurrent test number of threads, be tasks leave number of concurrent when the residue concurrent test number of threads of this test assignment is less than the available concurrent test number of threads of this test node, namely its maximum capacity performs this test assignment to the greatest extent, and revises the available concurrent test number of threads of corresponding cloud test node.If total concurrent test number of threads of this test assignment is assigned or the list of unshared cloud test node has been sky, then stop;
If three is that the concurrent test thread of this test assignment is also unallocated complete, continue to distribute concurrent test thread, until the concurrent test thread of test assignment is assigned to each cloud test node in the list of shared cloud test node successively with the method for salary distribution of similar above-mentioned steps;
Four is two the concurrent thread series of distribution returning this test assignment: the concurrent thread series of distribution of unshared cloud test node and shared cloud test node.
By using NSF dispatching algorithm, the ARUR of cloud testing apparatus can significantly improve.Such as shown in Fig. 3 a and Fig. 3 b, suppose to receive two test assignment: T1 and T2 in same △ t, the concurrent test number of threads that they need separately is respectively 200,220, and the original concurrent test thread threshold of each cloud test node can be as shown, the original concurrent test thread threshold of cloud test node A ~ F is 80,60,100,50,60,90, wherein.Test assignment T1 needs to use A, B, C, D tetra-cloud test nodes are tested, and T2 needs to use C, D, E, F tetra-cloud test nodes, i.e. C, D is the cloud test node that they are shared, as shown in Figure 3 a, adopt the strategy divided equally that the concurrent test thread of test assignment T1 is all assigned to A, B, C, after D tetra-cloud test nodes, concurrent test number of threads on these four cloud test nodes is 50, A, B, on C tri-cloud test nodes, remaining available concurrent test number of threads is 30, 10 and 50, on cloud test node D, remaining available concurrent test thread is zero, T2 then cannot carry out task matching, can only wait for and can use cloud test node D after T1 is finished.As shown in Figure 3 b, according to NSF dispatching algorithm, T1 takies cloud test node A and B, and 60 available concurrent test threads on cloud test node C, T2 takies cloud test node D, E and F, and 20 available concurrent test threads on cloud test node, then two test assignments can perform simultaneously.Like this, under two kinds of different situations, execute the time period interior (supposing that T1 and the T2 time of implementation is identical) of T1, be respectively 45.5% and 95% according to the ARUR that above-mentioned formulae discovery obtains, be significantly increased.
In the above embodiment of the present invention, if test assignment requires the concurrent test number of threads progressively increased Web service load cloud test to test it, such as require from concurrent test number of threads be 10,20,30,40 ... 100 test Web service load successively, time above-mentioned test process needs longer, then in Web service load cloud test process, after executing a test subtask, can again obtain the plural cloud test node carrying out Web service load cloud test at every turn; And be described plural cloud test node distribution concurrent test thread again, and concurrent test thread on described plural cloud test node ready after, send test instruction to it.
