解析Excel，通过Excel驱动测试数据参数化

1.解析Excel：

public class ExcelDataProvider  implements Iterator<Object[]>{
private Workbook book = null;
private Sheet sheet = null;
private int rowNum = 0;
private int curPhysicalRowNo = 0;
private int columnNum = 0;
private String[] columnnName;

public ExcelDataProvider(String classname, String methodname)throws BiffException, IOException {

File directory = new File(".");

this.book = Workbook.getWorkbook(new File(directory.getCanonicalPath()+ "\\filepath\\" + classname.replaceAll("\\.", "/") + ".xls"));
System.out.println(directory.getCanonicalPath() + "\\filepath\\"+ classname.replaceAll("\\.", "/") + ".xls");

this.sheet = book.getSheet(methodname);
this.rowNum = sheet.getRows();
//System.out.println(rowNum);
Cell[] c = sheet.getRow(0);
/* for(Cell c1:c){
System.out.println(c1.getContents());
}*/
this.columnNum = c.length;
//System.out.println(columnNum);
columnnName = new String[c.length];
for (int i = 0; i < c.length; i++) {
columnnName[i] = c[i].getContents().toString().replace("\n", "");
}
this.curPhysicalRowNo++;

}
@Override
public boolean hasNext() {
if (this.rowNum == 0 || this.curPhysicalRowNo >= this.rowNum) {
try {
book.close();
} catch (Exception e) {
e.printStackTrace();
}
return false;
} else
return true;
}

@Override
public Object[] next() {
Map<String, ArrayList<String>> s = new HashMap<String, ArrayList<String>>();
int RangeRow = 1;
boolean ThisIsRange = false;
jxl.Range[] ranges = sheet.getMergedCells();

//首先要确定第一列占了几行，要区分 Range 还是 Row
for (jxl.Range space : ranges) {
if (space.getTopLeft().getColumn() == 0
&& space.getBottomRight().getColumn() == 0
&& space.getTopLeft().getRow() == this.curPhysicalRowNo) {

RangeRow = space.getBottomRight().getRow()
- space.getTopLeft().getRow() + 1;
ThisIsRange = true;
break;
}
}

for (int i = 0; i < this.columnNum; i++) {
ArrayList<String> temp = new ArrayList<String>();
if (ThisIsRange) {
if (i == 0) {
temp.add(sheet.getRow(this.curPhysicalRowNo)[i].getContents().toString());

} else {
for (int j = 0; j < RangeRow; j++) {
temp.add(sheet.getRow(this.curPhysicalRowNo + j)[i].getContents().toString());

}
}
} else {
temp.add(sheet.getRow(this.curPhysicalRowNo)[i].getContents().toString());

}
s.put(this.columnnName[i], temp);
}
Object r[] = new Object[1];
r[0] = s;
this.curPhysicalRowNo = this.curPhysicalRowNo + RangeRow;

return r;
}
@Override
public void remove() {
throw new UnsupportedOperationException("remove unsupported.");

}

}

2.测试方法中调用dataProvider，将测试数据参数化：

方式一：直接定义数据

@Test(dataProvider = "dp")
public void testA(Map<String, ArrayList<String>> data) {
System.out.println(data.toString());

System.out.println("------------------");

System.out.print("字段A:" + data.get("字段A"));
System.out.println("");
System.out.print("字段B:" + data.get("字段B"));
System.out.println("");
System.out.print("字段C:" + data.get("字段C"));
System.out.println("");
System.out.print("字段D:" + data.get("字段D"));
System.out.println("");
System.out.println("*******************");

}

@DataProvider(name="dp")
public Iterator<Object[]> dataFortestMethod(Method method)throws IOException, BiffException {
return new ExcelDataProvider(this.getClass().getName(), method.getName());

}

方式二：

通过数据持久化层，将Excel中的数据值赋予给变量

数据持久化层：

public class Enterprise_reporting_demo {
public String standardId;
public String evaluateDate;
public String evaluateMan;
public String evaluateJoiner;

public Enterprise_reporting_demo(String standardId,String evaluateDate,String evaluateMan,String evaluateJoiner){
this.standardId=standardId;
this.evaluateDate=evaluateDate;
this.evaluateMan=evaluateMan;
this.evaluateJoiner=evaluateJoiner;
}

}

测试方法中调用：

@Test(dataProvider="dp")
public void test5(Map<String,ArrayList<String>>data){
Enterprise_reporting_demo enterprise_reporting_demo=new Enterprise_reporting_demo(data.get("standardId").get(0), data.get("evaluateDate").get(0), data.get("evaluateMan").get(0), data.get("evaluateJoiner").get(0));
enterprise_reporting.del_Enterprise_reporting(enterprise_reporting_demo);
Assert.assertFalse(enterprise_reporting.del);
}
@DataProvider(name="dp")
public Iterator<Object[]> dataFortestMethod(Method method)throws IOException, BiffException {
return new ExcelDataProvider(this.getClass().getName(), method.getName());

}

注意：Excel文件的命名应该和测试方法的命名一致，否则会提示：找不到文件
