In addition; The Auto-Test System of Dynamic Host Configuration Protocol server of the present invention also comprises a storage element 60 and a form generation unit 70; This storage element 60 is connected with this automatic test module 30 and this operating unit 20, and this form generation unit 70 is connected with this operating unit 20, this storage element 60 and this automatic test module 30.Whereby; This storage element 60 stores the data that this automatic test module 30 is tested; And this form generation unit 70 in order to the information of this automatic test module 30 of direct reception to produce form; Perhaps select the information in this storage element 60 by this operating unit 20, and produce form by this form generation unit 70 by user 10.
See also Fig. 2, it is the testing procedure schematic flow sheet of one embodiment of the present invention, and please cooperate and consult Fig. 1, and this steps flow chart includes S1-S11 totally ten one steps, explains as follows:
S1: produce and transmit a DHCPDISCOVERY package; This positive test unit 31 produces this DHCPDISCOVERY package according to RFC 2131 standards through this packet processing unit 40 and gives this Dynamic Host Configuration Protocol server 50; And wait for a corresponding DHCPOFFER package, wherein this DHCPDISCOVERY package and this DHCPOFFER package are respectively this positive test package 41 and this positive response package 42;
S2: the DHCPOFFER package of resolving passback; This positive test unit 31 is resolved and be sent to this packet processing unit 40 after receiving this DHCPOFFER package; By the Transaction ID in this positive test unit 31 these DHCPOFFER packages of inspection whether with this DHCPDISCOVERY package in Transaction ID identical, if come to the same thing, then represent test result normal; If Transaction ID is inequality, then test result is undesired;
S3: produce and transmit a DHCPREQUEST package; This positive test unit 31 produces this DHCPREQUEST package according to RFC 2131 standards through this packet processing unit 40 and gives this Dynamic Host Configuration Protocol server 50; And wait for a corresponding DHCPACK package, wherein this DHCPREQUEST package and this DHCPACK package are respectively this positive test package 41 and this positive response package 42;
S4: resolve this DHCPACK package; This positive test unit 31 is resolved and be sent to this packet processing unit 40 after receiving this DHCPOFFER package; By the Transaction ID in this positive test unit 31 these DHCPACK packages of inspection whether with this DHCPREQUEST package in Transaction ID identical, then check yiaddr field, verify whether it obtains correct IP address; If above checking is all correct; Then test result is normal, if incorrect, then test result is undesired;
S5: the test network accessibility, whether examination can utilize the IP address of being obtained by this Dynamic Host Configuration Protocol server 50 to carry out the network service access;
S6: check this DHCPACK package; This authentication unit 33 is resolved checking according to this DHCPACK package; Respectively to server ID (Sever Identifier), name server (Domain Name Sever; DNS) and the correctness of lease time (Lease Time) verify that and the IP address obtained of checking is whether in correct scope;
S7: carry out negative testing one; This negative testing package 43 is to be that a DHCPDISCOVERY contains wrong package according to RFC 2131 standards; Contain wrong package (it contains the error code of op code=0x03) to this Dynamic Host Configuration Protocol server 50 by sending this DHCPDISCOVERY; What need to specify is, wherein op code should be 0x01 and is only right value, and this Dynamic Host Configuration Protocol server 50 must be able to abandon the vicious DHCPDISCOVERY of these field contents and contain wrong package; Do not return the DHCPOFFER package, and can continue normal operation just for correct response;
S8: carry out negative testing two; The DHCPDISCOVERY that transmission one contains Flags=0x0001 contains wrong package and gives this Dynamic Host Configuration Protocol server 50; Wherein Flags should be 0x8000 and is only right value; This Dynamic Host Configuration Protocol server 50 must be able to abandon the vicious DHCPDISCOVERY of these field contents and contain wrong package, does not return the DHCPOFFER package, and can continue normal operation just for correct response;
S9: carry out negative testing three; The DHCPDISCOVERY that transmission one contains Ciaddr=224.168.0.1 contains wrong package and gives this Dynamic Host Configuration Protocol server 50; Wherein Ciaddr should be 0.0.0.0 and is only right value; This Dynamic Host Configuration Protocol server 50 must be able to abandon the vicious DHCPDISCOVERY of these field contents and contain wrong package, does not return the DHCPOFFER package, and can continue normal operation just for correct response;
S10: the running of checking main frame is normal; Because this Dynamic Host Configuration Protocol server 50 can not return the DHCPOFFER package receiving after the vicious DHCPDISCOVERY of field contents contains wrong package; And this Dynamic Host Configuration Protocol server 50 also can not return the DHCPOFFER package when fault, therefore, and after confirming above-mentioned negative testing; Must repeat step S1-S6 again one time, be under normal operation, to abandon wrong package to confirm this Dynamic Host Configuration Protocol server 50;
S11: form produces, and produces the report after this automatic test module 30 is tested by this form generation unit 70, checks for the tester.
Please cooperate and consult Fig. 3, it is the test result form example schematic of one embodiment of the present invention, and is as shown in the figure; If test result is normal, end product field (Result) can show PASS, if test result is undesired; End product field (Result) can show FAIL, and is as shown in the figure, wherein; Last two is negative testing, and this Dynamic Host Configuration Protocol server 50 should abandon after receiving the DHCPDISCOVERY mistake package that contains error field, and does not return the DHCPOFFER package; But this Dynamic Host Configuration Protocol server 50 can return the DHCPOFFER package, so test result is undesired, and report shows FAIL.
What need special instruction is; Much more no longer English proper nouns such as the DHCPDISCOVERY that is carried among the present invention, DHCPOFFER, DHCPREQUEST, DHCPACK, Transaction ID, yiaddr and Ciaddr are all has the noun that common knowledge the knowledgeable is known in this area, therefore to do explanation.
In sum; Because the present invention carries out functional test by 30 pairs of these Dynamic Host Configuration Protocol server 50 of this automatic test module; Not only can before this Dynamic Host Configuration Protocol server 50 dispatches from the factory, test, also can after tough body renewal or maintenance, carry out functional test to guarantee the machine quality.In addition, Auto-Test System of the present invention is avoided the tester because lack experience or careless mistake, causes erroneous judgement, or makes mistake when filling in the testing journal sheet, causes total quality to reduce, and causes company's loss.And, utilize storage element 60 of the present invention and this form generation unit 70 to store and the printing test result, convenient follow-up tracking and processing.In addition, compare with the manual detection mode, not only correctness is high to utilize Auto-Test System of the present invention, also can accelerate the time that QC detects, so the present invention has progressive and meets the important document of applying for patent of invention.
Below the present invention is done a detailed description, the above is merely a preferred embodiment of the present invention, when not limiting the scope that the present invention implements.Be that all equalizations of doing according to application range of the present invention change and modify etc., all should still belong in the patent covering scope of the present invention.
