s110: acquiring a register read-write instruction triggered by a device driving unit in response to a received input parameter; the device driving unit is used for driving hardware devices comprising preset registers, and the register read-write instruction is used for executing read-write operation aiming at the preset registers.
The device driving unit includes various driving units for driving hardware devices, and may be implemented by, for example, a driving software, a driving program, and the like. The hardware device to be driven is provided with a preset register, and the register is a hardware register and is positioned inside the hardware device.
In the working process, the device driving unit needs to perform read-write operation on a preset register inside the hardware device. For example, when the device driving unit receives an input parameter, a corresponding register read-write instruction is triggered according to a parameter value of the input parameter, so as to implement a read-write process on a preset register.
S120: remapping the read-write instruction of the register to the virtual register according to the address remapping mode; the virtual register is realized through a memory and is used for simulating a preset register.
In this embodiment, in order to simplify the test environment, a virtual register is set in the memory in advance, so that the virtual register simulates a preset register in the hardware device, thereby implementing the test process without the hardware device.
The register read-write instruction is remapped to the virtual register in an address remapping mode, so that the read-write instruction triggered by the device driving unit aiming at the preset register in the hardware device is redirected to the virtual register in the memory, and the effect of simulating the preset register in the hardware device by the virtual register is achieved.
S130: and acquiring a read-write operation result of the virtual register responding to the register read-write instruction, matching the read-write operation result with a standard read-write result corresponding to the input parameter, and determining a test result of the device driving unit according to the matching result.

And reading a read-write operation result generated by the virtual register, and matching the read-write operation result with a standard read-write result corresponding to the input parameter, so as to determine a test result of the device driving unit according to the matching result.
Wherein, a standard reading and writing result corresponding to the input parameter is determined in advance through calculation and the like, and the standard reading and writing result refers to: and under the condition that the equipment driving unit works normally, responding to the input parameters, and performing read-write operation on the register to generate a result. If the read-write operation result is matched with the standard read-write result, the test result is normal; if the read-write operation result is not matched with the standard read-write result, the test result is abnormal.
In the method for testing the device driving unit provided by the embodiment of the invention, the testing process can be realized by directly utilizing the local memory without hardware equipment, so that the testing environment is simplified, and the testing cost is reduced. Moreover, the read-write operation result of the virtual register is matched with the standard read-write result corresponding to the input parameter, so that the comparison efficiency of the test result can be improved, and the problem that manual judgment causes complexity and error easily is solved.
For the sake of understanding, a detailed description will be given below by taking a specific embodiment as an example.
Fig. 2 is a schematic diagram showing a structure of a test system in the related art. As shown in fig. 2, the test system includes: a device driving unit 21, a hardware device 22. Wherein the hardware device 22 further comprises: a first preset register 221, a second preset register 222, and a hardware circuit 223. Among them, the device driving unit 21 is used to drive the hardware circuit 223 in the hardware device 22. In addition, during the operation of the device driving unit, the first preset register 221 and the second preset register 222 need to be read and written.
In case of input parameter determination, data is written into the first preset register 221 and/or the second preset register 222 by the device driving unit, so as to drive the hardware circuit to generate a corresponding output result according to the data content. For example, when a hardware circuit has a plurality of operating states, the correspondence between different values of the register and the various operating states of the hardware circuit is set in advance. Accordingly, based on the correspondence, the circuit operation result corresponding to the data content in the register can be determined.
In the test system shown in fig. 2, after the hardware circuit reads the register value and displays the circuit operation result corresponding to the register value, it is determined whether the circuit operation state is normal by obtaining the circuit operation result, and it is further determined whether the device driving unit is normal. The circuit operation result can also be a software operation result, observable objects such as currently output circuit waveforms, logs, nixie tubes, display screens and the like need to be recorded for judgment, the purpose of automatically judging the result cannot be achieved in some scenes, and whether the result is correct or not needs to be determined by means of manual observation and recording and the like.
It can be seen that the system shown in fig. 2 has at least the following drawbacks and disadvantages: because hardware equipment is required to participate in the test process, more equipment is required for testing, and the environment is complex to set up; moreover, the test process result of a single case needs to be observed and recorded, and the test period is longer under the condition of more cases; moreover, the test result needs to be judged manually, and an objective factor exists.
In order to solve the above problem, fig. 3 is a flowchart illustrating a method for testing a device driving unit according to another embodiment of the present invention. In the embodiment shown in fig. 3, the hardware device is omitted, and the test of the device driving unit can be completed directly in the local of the test device. As shown in fig. 3, the method includes:
s300: and configuring a virtual register corresponding to the preset register in the memory of the test equipment according to the register configuration information of the preset register contained in the hardware equipment.
The method comprises the steps of obtaining register configuration information of a preset register, applying for a continuous memory space matched with the register configuration information, configuring the continuous memory space into a virtual register corresponding to the preset register, and storing a mapping relation between the virtual register and the preset register so as to realize address remapping processing in the subsequent steps. The number of the preset registers may be one or more. In this embodiment, the preset register includes: at least two first registers, respectively, a virtual register comprising: at least two second registers corresponding to the respective first registers.
The register configuration information of the preset register comprises at least one of the following: the identification of each first register, the numerical value of each first register, the bit width of each first register, the physical address information of each first register, and the attribute description information of each first register. The identifier of the first register may be information such as a name or an ID of the first register. The value of the first register is typically a value in the form of 0, 1. The bit width of the first register is also called the length of the first register, and is used for indicating the number of bytes occupied by the first register. The physical address information of the first register includes: the first register has specific information such as a start bit and an end bit of a physical address (also called a byte address) in the hardware device. The attribute description information of the first register is used to describe information such as a function and a structure of the first register. In short, the present invention does not limit the specific meaning of the register configuration information.
The register configuration information can be stored in a register list, wherein the configuration information is fixed except that the value of the register is variable, the format of the register list is not changed for fixed hardware design, and the register list can exist in the test equipment in a template form, so that the test equipment can directly and quickly create the virtual register in the memory according to the register configuration information stored in the register list.
The virtual register in the memory comprises a plurality of second registers, so when a continuous memory space matched with the register configuration information is applied and the continuous memory space is configured as the virtual register corresponding to the preset register, the address interval of the continuous memory space and the address range of each second register are determined specifically according to the bit width of each first register, so that the plurality of second registers are configured in the continuous memory space.
S310: the input parameters are sent to the device driving unit.
The execution subject of the method is test software running on the test equipment. In addition, the device driving unit can be device driving software, correspondingly, the testing software and the device driving software are both configured on the same testing device, and hardware devices driven by the device driving software do not need to be configured additionally, so that a testing result can be directly generated locally on the testing device, and the testing cost is reduced. In other words, the main execution body of the method is a test device (for example, test software installed on the test device) independent of the hardware device, and the device driver unit runs in the test device.
In this embodiment, the standard read/write result corresponding to the input parameter is configured in advance. When the input parameters are multiple groups, the standard read-write results corresponding to the input parameters of each group can be configured respectively. Correspondingly, all the input parameters are sequentially sent to the equipment driving unit, and judgment is carried out according to the matching relation between the read-write operation result corresponding to each input parameter and the standard read-write result. For example, when the device driving unit has a plurality of test cases, input parameters corresponding to the respective test cases and standard read-write results corresponding to the input parameters are configured, respectively. By means of sequentially sending a plurality of input parameters to the equipment driving unit, sequential testing of a plurality of test cases is achieved, and testing efficiency is greatly improved.
S320: and the acquisition equipment driving unit responds to the register read-write instruction triggered by the received input parameters.
In the working process of the device driving unit, read-write operation needs to be performed on a preset register inside the hardware device. For example, when the device driving unit receives an input parameter, a corresponding register read-write instruction is triggered according to a parameter value of the input parameter, so as to implement a read-write process on a preset register.
In this embodiment, in order to perform a test without relying on the hardware device, a read-write interface needs to be set in the test software, and the read-write interface can be implemented by a read-write function, so that the read-write interface intercepts a register read-write instruction triggered by the device driving unit in response to the received input parameter, and redirects the register read-write instruction in a subsequent step.
S330: and remapping the read-write instruction of the register to the virtual register according to the address remapping mode.
And sending the register read-write instruction to the virtual register in an address remapping mode according to the mapping relation mentioned above. For example, under the condition that the virtual register comprises a plurality of second registers, the register identifier contained in the register read-write instruction is analyzed and obtained, and the second registers corresponding to the register identifier are determined; and sending the register read-write instruction to a second register in an address remapping mode according to the mapping relation.
In one implementation, the memory absolute address can be translated for access in a manner consistent with the address space encoding of the hardware register (i.e., the default register). For example, the first address of the memory region corresponding to the virtual register can be pointed to by a manner similar to a data pointer in C language. In addition, in the case that the virtual register includes a plurality of second registers, the data pointer is specifically an array pointer, and each element in the array pointer is used for pointing to a corresponding second register. Correspondingly, the read-write interface can transfer the register read-write instruction triggered by the device driving software to the virtual register realized by the memory in a data pointer mode.
S340: and acquiring a read-write operation result of the virtual register responding to the register read-write instruction, matching the read-write operation result with a standard read-write result corresponding to the input parameter, and determining a test result of the device driving unit according to the matching result.
The virtual register responds to the register read-write instruction and generates a read-write operation result. And reading a read-write operation result generated by the virtual register, and matching the read-write operation result with a standard read-write result corresponding to the input parameter, so as to determine a test result of the device driving unit according to the matching result. If the read-write operation result is successfully matched with the standard read-write result corresponding to the input parameter, determining that the equipment driving unit is in a normal state; and if the read-write operation result is not matched with the standard read-write result corresponding to the input parameter, determining that the equipment driving unit is in an abnormal state.
The reading and writing operation result can be presented in a mode of reading and writing the result list through the register, the standard reading and writing result can be presented in a mode of presetting the result list through the register, the result list is preset through the pre-stored register, and judgment is carried out in a mode of comparing whether the read and writing result list of the register is matched with the result list of the register or not. For example, for a single test case, it corresponds to two register lists: one is a preset correct result (i.e. register preset result list); the other is the result of the device driver software running (i.e. the register read-write result list), which is generated by filling the value stored in the virtual register set after the software running into the register value field in the register read-write result list. During comparison, the register value fields in the register preset result list and the register read-write result list are compared. If the register value fields are the same, the register value fields are successful; if the register value fields are different, then failure occurs. Wherein the register value field is used to store the value of the register.
In conclusion, the testing method is realized by adopting software, the automation degree is high, and the judgment result is objective and does not depend on human judgment. The method can solve the problems that the testing device is complex, a single test case needs a complex recording process, results need manual judgment and the like in the prior art, and effectively overcomes the defects of low efficiency, high complexity, long testing period and the like. The plurality of second registers form a virtual register set, and a result can be obtained directly in a software input and output mode without hardware equipment. The test result clearly indicates pass or fail, and the comparison difference result can be displayed when the test result fails, so that the abnormity reason judgment can be conveniently carried out by comparing the difference result, and the implementation mode is simple and clear. The method can be completely separated from hardware equipment and circuits, the result of whether the driving software is qualified or not is completely given by logic test, and the test case can be repeatedly used. The method can solve the problems of low efficiency, complex test environment, inaccuracy caused by dependence on artificial observation of results and the like in the conventional method. The software testing process is automatically realized, the result is clear, and the tracking and the correction are convenient.
