Description
Technical field
The present invention relates to software testing technology field, and in particular to a kind of automatic test side of automatic decision start blank screen
Method.
Background technology
The standby start of TV at present can accidental or certain probability appearance start blank screen or the sound situation of blank screen, in order to multiple
Existing this kind of BUG is with the pressure verification after progress Resolving probiems, it is necessary to carry out constantly standby start test.
Generally use artificial manually operated remote control carries out switching on and shutting down in the prior art, and user observes the mode seen
To judge whether blank screen phenomenon occur, waste time and energy.
The content of the invention
The technical problems to be solved by the invention are：A kind of automated testing method of automatic decision start blank screen is proposed,
Conventional art is solved the problems, such as by being wasted time and energy existing for artificial judgment blank screen phenomenon.
The technical solution adopted by the present invention is as follows：
A kind of automated testing method of automatic decision start blank screen, comprises the following steps：
A. dress pastes brightness impression frock on the tv screen；
B. automatic test fixture control television startup, into testing source；
C. fixed white field signal is inputted to testing source；
D. automatic test fixture judges whether blank screen phenomenon occur by monitoring the output signal of brightness impression frock, if
Occur, then into step f, if not occurring, into step e；
E. automatic test fixture control television standby, return to step b continue to test；
F. automatic test fixture stops test, retains problematic phenomenon and prompts tester.
As further optimization, the brightness impression frock includes：Photodiode, triode, first resistor and second
Resistance；The photodiode is connected between the colelctor electrode of triode and base stage, and the first resistor is connected to photosensitive two pole
Between pipe and ground；The colelctor electrode of the triode connects VCC power supplys, and emitter stage is grounded by second resistance, and its emitter voltage is
The monitoring output signal of brightness impression frock.
Optimize as further, in step b, the automatic test fixture is good for code value to control by sending power supply to TV
NTSC television system NTSC is started shooting.
Optimize as further, in step d, output of the automatic test fixture by monitoring brightness impression frock is believed
Number judge whether that blank screen phenomenon occur specifically includes：
Automatic test fixture by the output voltage of brightness impression frock compared with default threshold voltage, if output
Voltage is more than or equal to threshold voltage, then judges that TV does not occur blank screen phenomenon；If output voltage is less than threshold voltage, judge
There is blank screen phenomenon in TV.
Optimize as further, in step e, the automatic test work is good for code value to control by sending power supply to TV
NTSC television system NTSC is standby.
The beneficial effects of the invention are as follows：Television startup, standby test are controlled by automatic test fixture, it is not necessary to test
Personnel control remote controller operation manually, convenient and swift；White field signal under testing source is detected by brightness impression frock, by
This judges whether the voltage output of monitoring point reaches threshold voltage, so as to which whether automatic decision blank screen occurs, it is not necessary to tester
Member's human eye viewing judges, improves test accuracy and efficiency, reduces artificial participate in.
Brief description of the drawings
Fig. 1 is the automated testing method flow chart of the automatic decision start blank screen in the embodiment of the present invention；
Fig. 2 is a kind of example structure schematic diagram of brightness impression frock.
Embodiment
The present invention is directed to propose a kind of automated testing method of automatic decision start blank screen, solves conventional art and passes through people
The problem of work judges to waste time and energy existing for blank screen phenomenon.Its core be by automatic test fixture control television startup,
It is standby, blank screen phenomenon is tested by brightness impression frock, so as to realize the automatic test to blank screen of starting shooting.
It should be noted that " automatic test fixture " in the present invention is the application software write according to testing requirement,
It can be carried in PC, and being communicated by PC with television set can be achieved switching on and shutting down of the automatic test fixture to television set
Control and the monitoring of output voltage signal to brightness impression frock, those skilled in the art hold very much according to the description of the present application
Easily realize, no longer its particular content construction is repeated here.
Below in conjunction with the accompanying drawings and embodiment the solution of the present invention is further described：
In 648 movement software tests, for exchange start, it is standby start, quick turn-on can accidental appearance start shooting it is black
Screen problem；To reappear the pressure test of the checking after this kind of BUG and BUG are solved, we just pass through the automatic test on computer
Frock connects television set, controls TV turning on-off, the work of brightness impression is made using the characteristic of photodiode " photoconduction "
Dress, so that it may start blank screen is judged with automatic test entirely.
It is as shown in Figure 1 to implement step：
1. dress patch brightness impression frock on the tv screen；
2. after electricity is exchanged to television set, automatic test fixture control television startup, into testing source；
3. fixed white field signal is inputted to testing source；
4. automatic test fixture judges whether blank screen phenomenon occur by monitoring the output signal of brightness impression frock, if
Occur, then into step 6, if not occurring, into step 5；
5. automatic test fixture controls television standby, return to step 2 continues to test；
6. automatic test fixture stops test, retain problematic phenomenon and prompt tester.
One example of the brightness impression frock made in the present invention is as shown in Fig. 2 it includes photodiode D1, three poles
Pipe Q1, first resistor R1 and second resistance R2；The photodiode D1 is connected between triode Q1 colelctor electrode and base stage,
The first resistor R1 is connected between photodiode D1 and ground；The colelctor electrode of the triode Q1 connects VCC power supplys, emitter stage
It is grounded by second resistance R2, its emitter voltage is the monitoring output signal Vout of brightness impression frock.
After controlling television set quick turn-on in the strong code value that power key is sent by automatic test fixture, believe to test
The fixed white field signal of number source input, if normally white field, photodiode D1 experience the white field on screen to starting-up image
The illumination of brightness so that photodiode D1 is turned on, and triode Q1 is amplified to electric current, the Vout output voltage in monitoring point
Also default threshold value can be reached, so as to judge that start is normal；, whereas if start blank screen, then photodiode D1 cut-offs, three poles
Pipe Q1 is also switched off, and in monitoring point, Vout output voltage is less than default threshold value, so as to judge blank screen of starting shooting.
If starting shooting blank screen, automatic test fixture stops operation, and retains problematic phenomenon and prompts tester, so as to
It is easy to bug processing.If start is normal, automatic test fixture control television standby, and prepare second of start test.
