In step 2, the inserting position of time recording instruction can require to insert the appropriate position in loading program according to actual test
Set, test equipment EasyTime obtains the called allocating time of inserting function, and calculate automatically call between function when
Between be spaced, test result is exported to interface and is shown；It such as needs to test other times, is then adjusted and inserted according to testing requirement
The position of function.
In step 3, test equipment EasyTime can monitor the time parameter of each cycle of operation, to realize to embedding
The complete monitoring for entering formula software operating condition solves the problems, such as to be difficult to find accidental error.
In step 4, measurement result can be recorded and generate test report by test equipment EasyTime, when necessary may be used
Using as test evidence for supervisor, developer and tester carry out using.
In view of the deficienciess of the prior art, test equipment EasyTime provided by the invention perfectly solves this hardly possible
Topic, specifically has the beneficial effect that:
1, easy to operate, it, can be according to user as long as embedded software internal operation data can be obtained by conversion line
Demand Design production conversion line type, reach wide applicability；
2, without unpacking to measured piece in measurement process, measurement scene and the more adjunction of the true Run-time scenario of tested software
Closely, and in combination with the real-time characteristic of environment resistance test verifying software under different external environments；
3, time intuitive measurement results, complete, provide the authentic data of abundance for the time examination of embedded software；
4, test equipment is light small and exquisite, easy to carry, can carry out on-line testing in outfield；
5, it is with a low credibility to compensate for test result caused by the time test method disunity of embedded software；
6, time error caused by having evaded because of misoperation.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of test equipment EasyTime and measured piece.
Fig. 2 is that time recording instruction inserts schematic illustration.
Fig. 3 is test equipment EasyTime product figure.
Specific embodiment
Now in conjunction with attached drawing 1-3, invention is further described in detail:
A kind of on-line testing method of embedded software time response uses test equipment EasyTime comprising electricity
Source control module, display control module, I/O module, SCM system, energy supply control module carry out test equipment EasyTime
Power supply management；Display control module controls display interface, and inputs instruction display according to the button of user and correctly draw
Face；I/O module can determine the processing mode of data according to the input type (RS422 or RS232 or other) that user selects, and
And the data of record can be exported to computer by USB after receiving data export instruction；SCM system master
It is responsible for calculating the time, and calculated result is exported to display control module and is shown.
A kind of on-line testing method of embedded software time response, comprising the following steps:
Step 1 passes through RS422 or RS232 serial ports or other communication serial ports for test equipment EasyTime and measured piece phase
Even, connection schematic diagram is shown in Fig. 1；
Step 2 inserts time recording instruction into tested software, programming program, and time recording instruction inserting principle is shown in figure
2；
Step 3, runs software design test scene, and passage capacity test equipment EasyTime directly reads time parameter,
The time parameter read is corresponding with software cycle of operation number, and product schematic diagram is shown in Fig. 3；
After step 4, test, each time measured can be exported by test equipment EasyTime, for software
Developer and tester analyze and record.
In step 1, test equipment EasyTime only has unique USB port, and RS422 serial data is transferred as USB number
According to being different from the unpacking measurement method of tradition, exported measurement data by serial ports, design is succinct, can pass through conversion line and quilt
Survey part to be connected, while after test, can be attached by conversion line and computer, by test result be derived automatically to
In computer.In order to solve the problems, such as that embedded software communication interface model is numerous, conversion line is designed as can be from test equipment
The design easily removed in EasyTime selects different switching line according to different measured pieces, completely may be used just as mobile phone charging
Unpacking operation difficulty is avoided to realize the broad applicability of test equipment EasyTime with the connecter type for covering resident
Accidental damage big and to measured piece.
In step 2, the inserting position of time recording instruction can require to insert the appropriate position in loading program according to actual test
Set, test equipment EasyTime obtains the called allocating time of inserting function, and calculate automatically call between function when
Between be spaced, test result is exported to interface and is shown；It such as needs to test other times, is then adjusted and inserted according to testing requirement
The position of function, it is easy-to-use.The method of tradition acquisition low and high level is revised as acquisition time recording instruction by the present invention
Output time, be more nearly the true operating status of software, confidence level is higher.And the position for inserting function is flexible, is suitable for
The time test of Embedded natural period test, runing time test and progress needed for other.
It is in step 3, software cycle of operation number is corresponding with the time measured, it realizes embedded software and is established by cable from above
Begin the whole measurement terminated to lower electricity, avoids and only measure 10 accidental errors using conventional test methodologies, to embedded software
The real-time of part can carry out whole process and clearly observe.
In step 4, the result measured can be preserved completely, provided for software developer and tester
Measurement data support, can preferably promote software quality, while it is real that a new software can be provided for supervisor
The report of when property test data, has greatly reinforced the quality of software.
Test equipment EasyTime as shown in Figure 3, " power supply " button are the switching on and shutting down button of test equipment EasyTime；
It is different according to the conversion line type used, corresponding interface, test equipment are selected by the button in interface selectionbar
EasyTime can carry out communication adaptation automatically, obtain test result；" rolling " button then can choose scrolling display or freeze
The test result that current interface is shown facilitates user's real-time perfoming data record and analysis, again taps on scroll button and then cancels
Interface locking continues to show most recent measurements；When display interface freezes, " turning over " button and " under turn over " button can be passed through
Selection display test result when scrolling display, is turned over to turn over under and is not responded to operation.
