# 13-validation-nodup: Field Validation (No Duplicates)
|
|
|
|
## 电信业务场景
|
|
|
|
CDR字段校验。对CDR记录进行字段值校验，检查通话类型代码是否为有效值(01/02/03)，有效记录输出到GOOD文件，无效记录输出到BAD文件。
|
|
|
|
## Description
|
|
|
|
Reads FILE-IN and validates FIELD1 against an allowed-value list
|
|
('A', 'B', 'C', 'D', 'E'). Records with valid FIELD1 values are
|
|
written to FILE-OUT-GOOD. Invalid records are written to
|
|
FILE-OUT-BAD with an error code appended.
|
|
|
|
## Record Layout
|
|
|
|
### Input / Good Output (31 bytes)
|
|
|
|
| Field | Type | Length | Description |
|
|
|--------|----------|--------|---------------------------|
|
|
| FIELD1 | PIC X | 1 | Validation field |
|
|
| FIELD2 | PIC X | 30 | Description / payload |
|
|
|
|
### Bad Output (33 bytes)
|
|
|
|
| Field | Type | Length | Description |
|
|
|----------|----------|--------|---------------------------|
|
|
| FIELD1 | PIC X | 1 | Original invalid value |
|
|
| FIELD2 | PIC X | 30 | Original description |
|
|
| ERR-CODE | PIC X | 2 | Error code ('01') |
|
|

## Tests
|
|
|
|
| Test Case | Description |
|
|
|----------------------------|-----------------------------------------|
|
|
| Valid values A-E | All 5 allowed values pass to GOOD |
|
|
| Invalid values X,Y,Z | Non-allowed alpha values go to BAD |
|
|
| Invalid values 1,9 | Numeric values go to BAD |
|
|
| Empty FIELD1 (space) | Treated as invalid, goes to BAD |
|
|
| Error code in BAD output | '01' appended to each bad record |
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
cd 13-validation-nodup
|
|
bash data-gen.sh
|
|
bash run.sh
|
|
```
|
|
|
|
## Expected Behavior
|
|
|
|
- 5 valid records in FILE-OUT-GOOD (31 bytes each = 155 bytes)
|
|
- 6 invalid records in FILE-OUT-BAD (33 bytes each = 198 bytes)
|
|
- Invalid records contain the original data plus '01' error code
